Question

What is the shaded area???

Answer 1

Explanation:

`area \: of \: circle = \pi\:r^(2) \\ \pi *6.5^(2) - \pi * {2.3}^(2) = 36.96\pi = 116.113... {cm}^(2)`

Answer 2

116.129 cm²

Explanation:

Area of circle:

`\boxed{\bf Area \ of \ circle = \pi r^2}`

Area of outer circle:

R = 6.5 cm

Area =3.142 * 6.5 * 6.5

= 132.75 cm²

Area of inner circle:

r = 2.3 cm

Area of inner circle =3.142 * 2.3 *2.3

= 16.621 cm²

Area of shaded area = area of outer circle - area of inner circle

= 132.75 - 16.621

= 116.129 cm²
