can someone explain how to do circles and circumference
(geometry)

Answers

Answer 1

Answer:

Radius:

radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.

Diameter:

2 times the radius is the circle's diameter.

Circumference:

The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).

Answer:

The values that are in the correct spots are: 82, 62, 163 and 300

Step-by-step explanation:

There are 144 boys in total. We know that 82 attended the fall fling, so if we do 144-82 we know that 62 boys attended the spring social, therefore the vaules 82 and 62 are in the correct spots. We know that out of 156 girls, 75 attended the spring social. 156-75=81. The values 75 and 81 are in the wrong spots, therefore they are not correct.

82 boys + 81 girls at the fall fling = 163 total students at the fall fling, therefore 163 is also in the correct spot.

62 boys + 81 girls at the spring social = a total of 137. The chart says the total is 143 which is incorrect.

156 total boys plus 144 total girls = 300 total students, therefore 300 is in the correct spot.

Answer:

The values that are in the correct spots are: 82, 62, 163 and 300

ACD is a straight line= 180 degrees.
If angle BCD= 113 degrees,
then angle BCA= 180 - 113 degrees
= 67 degrees.
Sum of interior angles of a triangle= 180 degrees.
So, angle B= 180 - (72 + 67)
= 180 - 139
= 41 degrees.
Therefore, angle B = 41 degrees.

I hope I'm right :)

what are the angles of a triangle with 73, x, x-11?

Answers

Answer:

The angles of the triangle are 73, 59, and 48

Step-by-step explanation:

The sum of a triangle's angles must always add up to 180

In order to find out the measure of x we must make an equation where 180=the sum of the angles

180=2x+62

We got the 2x and the 62 from combining like terms

x+x=2x

73-11=62

Now we simply use algebra and try to solo out the x

First, subtract 62 from both sides

118=2x

Then, divide both sides by 2

59=x

x=59

Then plug in 59 with x and this gives you

73, 59, and 48 which all together add up to 180

What is Volume?

Volume is a term used in mathematics to describe how much three-dimensional space an item or closed surface occupies.

Given:

Cube: edge = 2.5 feet

Cuboid: l = 7.5 ft, w= 15 feet, h= 7.5 feet

So, Volume of cubical box

= l³

= 2.5³

= 15.625 ft³

and, Volume of Cuboidal box

= lwh

= 7.5 x 15 x 7.5

= 843.75 ft³

Dalia buys a winter jacket at a used clothing store that costs $30. She lives in Idaho, where the sales tax is 6%.




Write an equation that represents the total cost, c, of any item bought in Idaho whose price is p

Answers

Answer:

c = 0.06p + p

Step-by-step explanation:

hope this helped

An equation that represents the total cost, c, of any item bought in Idaho whose price is p is c = 1.06p.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Cost of the winter jacket = $30

Sales tax = 6%

Total cost of the winter jacket = 30 + (6% × 30)

                                                   = 30 + 1.8

                                                   = $31.8

If the total cost of any item is c whose price is p,

c = p + (6% × p)

c = p + 0.06p

c = 1.06p

Hence the required equation is c = 1.06p.
