a sphere has a radius of 6m
what measurement is the closest to the volume of the sphere in cubic inches?
Answer:
[tex]V=55212651.6\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
The radius of a sphere, r = 6 m
We know that,
1 m = 39.37 inches
6 m = 236.22 inches
The volume of the sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}\pi \times 236.22^3\\\\V=55212651.6\ \text{inches}^3[/tex]
So, the required volume of the sphere is equal to [tex]55212651.6\ \text{inches}^3[/tex].
a. Keiko's estimate for the distance the car will roll is 85 cm. What is the percent error in Keiko's estimate? Show your work.
Answer:
I believe it should be 5.882%

i’m confused on how to do this
Answer:
68°
Step-by-step explanation:
The sum of all internal angles of a circle always total 360°.
So, we can add the three angles (ADB, BDC, ADC) and equate them to 360°.
90 + (2x+1) + (2x-3) = 360
90 + 4x -2 = 360
4x - 2 = 360 - 90
4x - 2 = 270
4x = 272
x = 272/4
x = 68°
From here, you can find any of the two unknown angles by simply plugging in x = 68°.
Feel free to ask me if you didn't understand any part :D

cos B =
tan B =
sin B =
The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).
Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse
Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse
Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.
The acronym to remember this is SOHCAHTOA
SOH | CAH | TOA
SOH means sin(x) = opposite/hypotenuse
CAH means cos(x) = adjacent/hypotenuse
TOA means tan(x)= opposite/adjacent
cosB = length of adjacent side/length of hypotenuse = 7/25
tanB = length of opposite/length of adjacent = 24/7
sinB = length of opposite/length of hypotenuse = 24/25
Find the surface area and volume of the prism.

The volume of the prism is
cm?
The surface area of the prism is 456cm² and the volume is 408cm³
What is a prism?A prism is a solid shape that is bound on all its sides by plane faces. There are two types of faces in a prism. The top and bottom faces are identical and are called bases. A prism is named after the shape of these bases. For example, if a prism has a triangular base it is called a triangular prism.
here, we have,
The formula for the surface area of a prism is SA=2B+ph, where B, again, stands for the area of the base, p represents the perimeter of the base, and h stands for the height of the prism.
Base area = 1/2× 8× 6
= 4×6 = 24 cm²
perimeter of the base = 6+8+10 = 24cm²
therefore SA = 2(24)+24×17
= 48+408
= 456cm²
Volume of the prism = base area × height
= 24 × 17
= 408cm³

In the diagram, the measures of 22, 23 and 26 are 40°. The measure of 21
is 140°. Are lines cand d parallel?
Answer:
c. Yes because ∠2 and ∠6 are congruent.
Step-by-step explanation:
From the picture attached,
m(∠2) = m(∠3) = m(∠6) = 40°
m(∠1) = 140°
Since (∠2 ≅ ∠6) (corresponding angles)
Therefore, by the converse theorem of corresponding angles lines c and d are parallel.
Option c is the answer.

Jiro borrows $48000 from a bank that charges simple interest at a rate of 6% per year. Find the total amount of money he has to pay the bank at the end of 2 years.
Answer:
$53760
Step-by-step explanation:
Rui Feng borrows $48 000 from a bank that charges simple interest at a rate of 6% per annum.
Now, we have to calculate the total amount he has to pay the bank at the end of 2 years.
Now, using the formula of simple interest the total amount after 2 years will be

How do you solve a math problem but by using the chunking strategy.
Answer:
chunking is a maths method for dividing large numbers which can't be done mentally. It is the repeated subtraction of the divisor and its multiples. Put simply, it involves working out how many groups of a specific number fit into another number.

Given the diagram, a supplement to
Given:
The figure of a quadrilateral ABCD.
To find:
The supplement of angle ABC.
Solution:
We know that, two angles are called supplementary angles if their sum is 180 degrees.
[tex]\angle ABC+\angle BAC=110^\circ+40^\circ[/tex]
[tex]\angle ABC+\angle BAC=150^\circ\neq 180^\circ[/tex]
So, [tex]\angle BAC[/tex] is not a supplement of [tex]\angle ABC[/tex].
[tex]\angle ABC+\angle ADC=110^\circ+90^\circ[/tex]
[tex]\angle ABC+\angle ADC=200^\circ[/tex]
So, [tex]\angle ADC[/tex] is not a supplement of [tex]\angle ABC[/tex].
[tex]\angle ABC+\angle DAB=110^\circ+(40+30)^\circ[/tex]
[tex]\angle ABC+\angle DAB=110^\circ+70^\circ[/tex]
[tex]\angle ABC+\angle DAB=180^\circ[/tex]
So, [tex]\angle DAB[/tex] is a supplement of [tex]\angle ABC[/tex].
In the same way [tex]\angle ABC+\angle BDC\neq 180^\circ[/tex].
So, [tex]\angle BDC[/tex] is not a supplement of [tex]\angle ABC[/tex].
Therefore, the correct option is C.
A triangle has the coordinates

please help me i really need it
Answer:
top right is the hypotenuse, top left is a leg, bottom right is a leg
Step-by-step explanation:
Every triangle has 2 legs and 1 hypotenuse. The hypotenuse is always the longer side and across the 90 degree angle. All of the other sides would be called the legs because they are not the hypotenuse

6. The dimensions of a rectangular garden are 380ft x 250ft. If you want to walk around this garden to make 3 miles for a morning walk, how many times should you walk? Note: I mile 5280f.
Answer:
Step-by-step explanation:
L=3(5280)/(2(380+250))
L=15840/1260
L=12.57
So to walk three miles one must walk around the garden 12.57 times.

Corey needs at least 2 gallons of paint to make a mural. If Corey has 6 quarts and 3 pints of paint, will he be able to make a mural?
Answer:
no
Step-by-step explanation:
4 quarts = 1 gallon, so he would have 1.5 gallons.
8 pints = 1 gallon, he would need 4 pints to have 2 gallons
Answer:
No he will not.
Step-by-step explanation:
6 quarts to a gallon is 1.5
3 pints to a gallon is 0.375
you add those together you get 1.875 not 2
