Question

I just can't get the answer to this question...

Answer 1

490.87 cm^2 or 491 cm^2

Explanation:

by adding up the 2.5s from the center till the outer boundary, we can get the radius of the target. So= 2.5+2.5+2.5+2.5+2.5 which is = to 12.5 cm

12.5cm is the radius of the target

now by using the formula for area of a circle and by plugging in the 12.5 as radius we can get the area.

so,

A=πr^2

A=
`a=\pi *(12.5)^2`

that gives us 490.87 cm^2

which after rounding is

491 cm^2
