A square pyramid has side lengths each measuring 8 centimeters. The height of the pyramid is 3 centimeters What is the lateral area of the pyramid?
20 square centimeters
64 square centimeters
80 square centimeters
84 square centimeters
Answer:
C. 80 square centimeters
Step-by-step explanation:
Edge 2021
The lateral surface area of the given square pyramid is 80 cm².
What is lateral surface area?The lateral surface of an object is its entirety, excluding its base and top (when they exist).
Boundary - layer surface zone equals lateral surface area. This is to be contrasted from the total surface area, which includes the lateral surface area along with the base and top regions.
Given that, a square pyramid has side lengths each measuring 8 centimeters.
The height of the pyramid is 3 centimeters.
The lateral area of a square pyramid = 2al = 2a√[(a²/4) + h²]
= 2×8√[(8²/4) + 3²]
= 16√[(64/4) + 9]
= 16√[16 + 9]
= 16×5
= 80 cm²
Therefore, the lateral area of the pyramid is 80 cm².

In ABC with the right angle at vertex C, sin(b)= (26)/8. What is sin(a)?
Answer:
We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.
Step-by-step explanation:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.

Use the Arithmetic Series formula to calculate the sum:
-6+(-3)+0+ • • • + 162
(Hint: how many numbers are being added?)
Answer:
Step-by-step explanation:
The common difference is 3.
nth term = -6+(n-1)3
-6+(n-1)3 = 162
(n-1)3 = 168
n-1 = 56
n = 57
162 is the 57th term.
S₅₇ = 57×(a_1+a_{57})/2
= 57×(-6+162)/2
= 57×156/2
= 57×78
= 57×(-6+162)/2
= 4446

Answer:
7pi/theta = radius
Step-by-step explanation:
So we are using the arc length, central angle(in radians), and radius.
We know arc length, which is 7pi.
We don't know theta, which does not matter.
And finally, we don;t know radius, which is what we are looking for.
To find radius, we use:
arc length/theta=radius
Lets plug in our values:
7pi/theta=radius.
So the answer to the khan acadamy question is
7pi/∅
Here are some othr things that may help:
Radian * Radius = arc length
This solves for arc length
Here is another one:
Arc length/radius= radian
This solves for radians
Hope these help! :)

A square mirror has an area of 25 square feet. How long is each edge of the mirror?
write an explicit formula for an, the nth term of the sequence 11,2,-7
Answer:
[tex]a_{n}[/tex] = 20 - 9n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 2 - 11 = - 7 - 2 = - 9
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = - 9 , then
[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n

Answer:
[tex]22\ km[/tex]
Step-by-step explanation:
One is given the following information:
[tex]10\frac{1}{1}[/tex] km were covered on Thursday[tex]10\frac{1}{1}[/tex] km were covered on FridayOne is asked to find the total distance covered on both of these days. In order to do so, one must remember in a fraction, any number over (1) is equal to the numerator (number over the fraction bar). Thus one can form the following equation:
[tex](Thursday)+(Friday) = Total\ distance[/tex]
Substitute,
[tex](Thursday)+(Friday) = Total\ distance[/tex]
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
Simplify,
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
[tex](10+1)+(10+1) = Total\ distance[/tex]
[tex](11)+(11)=Total\ distance[/tex]
[tex]11+11=Total\ distance[/tex]
[tex]22=Total\ distance[/tex]

A running track has two semi-circular ends with radius 25m and two straights of length 87.6m as shown.
Calculate the total distance around the track rounded to 1 DP.
The total distance around the track is 332.2 meters
How to calculate the total distance?The complete question is in the attached image
The given parameters are:
Radius, r = 25 m
Length, l = 87.6 m
Start by calculating the circumference of the two semi-circular ends using:
[tex]C = 2\pi r[/tex]
So, we have:
C = 2* 3.14 * 25
Evaluate
C = 157
The total distance around the track is then calculated as:
Total = 2l + C
This gives
Total = 2 * 87.6 + 157
Evaluate
Total = 332.2
Hence, the total distance around the track is 332.2 meters

8x + 2y = 104
Is that possible, and if so, prove it pls
Mhanifa is the best user on Brainly
So, if I attract him, I will die
Answer:
Implicit Form: 4x + y - 52 = 0
Step-by-step explanation:
8x + 2y = 104 => Move constant to the left and change the sign
8x + 2y - 104 = 0 => Divide both sides of the equation by 2
4x + y - 52 = 0
