Question

Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π)

Answer 1

254.3

Explanation:

A = πr^(2) = π(9^(2)) = 81π = 254.34

Answer 2

78.5 centimeters squared

Explanation:

The area of a circle is given by:
`A=\pi r^(2)` , where r is the radius. In this case, the radius r = 5 and we are using 3.14 for
`\pi`. So, substituting these values, we have:

A =
`\pi r^(2) =3.14*5^2=3.14*25=78.5`

Thus, the area is 78.5 centimeters squared.

Hope this helps!
