Question

Finding the area of a circle with diameter 18yd use the value 3.14 for pi without rounding your answer

Answer 1

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

Answer 2

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
