Answer:
320.47in² or 320.47 (to the nearest hundredth)
Explanation:
The area of a circle that has a diameter of 20.2 inches is 320.47in².
Formulas: A=πr2 and d=2r
A=1/4πd2=1/4·π·20.22≈320.47387in²
320.31 in²
The area of a circle can be computed from ...
A = (π/4)d²
Filling in the numbers and doing the arithmetic, we get ...
A = (3.14/4)(20.2 in)² ≈ 320.31 in²
