Question

Determine the area of a circle whose diameter is 8 inches.... A.) 50.24 square inches B) 50.24 inches C) 200.96 square inches D) 200.96 inches...What's the answer guys...

Answer 1

We can find the area of any circle with the formula
`A = \pi r^2`
Where r is the radius. We have the diameter but we need the radius.

Luckily, finding the radius is easy if you have the diameter because the radius of half of the diameter.

8 / 2 = 4

And we will let
`\pi` = 3.14

A = (3.14)(4)^2
A = (3.14)(16)
A = 50.24

So, the area of the square is A) 50.24 square inches.
