Question

use 3.14 for pi to estimate the area of the circle. the diameter is 24.4 m. round your anser to the nearest hundredth if necessary.
A. 76.62 m squared
B. 1, 869.43 m squared
C.467.36 m squared
D. 38.31 m squared

Answer 1

its  the first choice A.76.62 m squared

Answer 2

Hey,
To find the area of a circle, the formula is pi times radius squared. Radius is half of diameter, to find radius divide diameter by 2.

Radius = 24.4 ÷ 2 = 12.2

Area = π • r²
Area = 3.14 • 12.2²
Area = 3.14 • 148.84
Area = 467.36 (467.3576 rounded to nearest hundredth)

Answer is C. 467.36
