NEED ALL THE ANSWERS FOR THE RADIUS , diameter , circumference , and area of this circle PLEASE ASAP :)

The radius of a circle is equal to one-half its diameter. The diameter is given on the circle, and is 15 in. Therefore, the radius is one-half of 15, or 7.5 in. The circumference of a circle can be found by multiplying pi by the diameter. So, the circumference is 15π in or approximately 47.1239 in. The area of a circle can be found using the equation pi times the radius squared, which for this circle would be 7.5^2 x pi. The area of the circle is equal to 56.25 π in^2 or 176.7146 in^2.

Diameter: 15 in

Radius: 7.5 in

Circumference: 15π in or 47.1239 in

Area: 56.25π in^2 or 176.7146 in^2

Explanations and Answers:

Ok so to do this you just need to plug a bunch of different numbers into a bunch of different formulas :)

Diameter:

The diameter is the distance from one side of the circle to the other. In this case it is the given value: 15

Radius:

The radius is the distance from the center to any point on the edge of the circle. It is also half of the diameter. So, in this case you just have to take the diameter and divide it by 2.

15÷2=7.5

Circumference:

The circumference is the distance around the entire outside of the circle (essentially the perimeter). To find the circumference you multiply the diameter by π (Unless told otherwise use 3.14 as π).

15×π=?

15×3.14=47.1

Area:

To find the area of a circle you have to square your radius (multiply it by itself) and then multiply that by π.

πr²=?

π×7.5²=?

π×56.25=?

3.14×56.25=176.625

If you need any more help or further explanations just let me know!!

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
