Answer:
(1) 2290.2 yd²
(2) 804.2 cm²
(3) 237.8 in²
(4) 1006.6 ft²
Step-by-step 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
