Answer:
A=254.47yd²
Explanation:
The area of a circle with diameter 18yd using the value 3.14 for pi without rounding the answer is, 254.47yd².
Formulas: A=πr² and d=2r
A=1
4πd²=1
4·π·18²≈254.469yd²
There is a special formula to find a circle's area when you know its diameter:
Circle Area = ¼ • π • d²
Circle Area = ¼ • 3.14 • 18²
Circle Area = ¼ • 3.14 • 324
Circle Area = .785 • 324
Circle Area = 254.34 square yards
