Question

A circle has a diameter of 16 units. What is the area of the circle to the nearest hundredth of a square unit?

Answer 1

Answer:

200.96 or 201

Step-by-step explanation:

The area of a circle is pi times R squared but the diameter is only given. so divide the diameter is halves. 16/2 is 8. Now is the raduis. plugging this info in, 8^2 is 64, and 64 times 3.14 (pi) is 200.96. Round that to the nearest hundredth and you get 201

Answer 2

Diameter = 2 times radius

16 = 2r

16/2 = r

8 = r
