Question

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. A circle has a diameter of 28 centimeters. Estimate the area of the circle. Use 22 7 for π .

Answer 1

Answer:

The area of the circle is $616\ cm^{2}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\pi r^{2}$

In this problem we have

$r=D/2=28/2=14\ cm$ ----> the radius is half the diameter

substitute

$A=(22/7)(14)^{2}=616\ cm^{2}$
