Question

PLEASE ANSWER ASAP FOR BRAINESLT!!!!!!!!!!!!!!!!!!

Answer 1

The area of this circle is 78.5

Explanation:

The area of a circle can be calculated with the equation πr². r stands for "radius", the distance between the center of the circle to any point of its edge which also equals to half of a circles diameter. Since the diameter of this circle is 10 in., its radius is

`r = d/2 = 10/2 = 5\\`

Then, we use this to find the area

Area =
`\pi r^2=\pi (5)^2=25\pi=78.5` (rounded to the first decimal place)

Answer 2

Explanation:

`a = \pi {r}^(2) \\ a = \pi {5}^(2) = 78.5 \: {in}^(2)`
