Answer:

(1) 2290.2 yd²

(2) 804.2 cm²

(3) 237.8 in²

(4) 1006.6 ft²

Explanation:

(1) Area (A) = πr²

A = πr² ....................... Equation 1

Given: r = 27 yd,

Substitute into equation 1

A = (π)×27²

A = 2290.2 yd²

(2) A = πr²................ Equation 2

Given: r = 16 cm

Substitute into equation 2

A = 16²(π)

A = 804.2 cm²

(3) A = πr²................... Equation 3

Given: r = 8.7 in

Substitute into equation 3

A = 8.7²(π)

A = 237.8 in²

(4) A = πr².............. Equation 4

Given: 17.9 ft

Substitute into equation 4

A = 17.9²(π)

A = 1006.6 ft²
