Question

A group of students stood in a circle to play a

game. The circle had a diameter of 22 meters.
Which measurement is closest to the area of the
circle in meters ?

Answer 1

Answer: Choice C) 379.94 square meters

=========================================================

Work Shown:

Diameter = 22 meters

Radius = 11 meters (half the diameter)

We'll plug r = 11 into the formula below

A = pi*r^2

A = 3.14*11^2

A = 379.94

This value is approximate since pi = 3.14 is approximate. Use more decimal digits of pi to get a more accurate area value.
