What is the area of a circle with a diameter of 15.8 cm? use 3.14 for pi and round your final answer to the nearest hundredth. enter your answer in the box. cm2

A=195.97 cm^2

Step-by-step explanation:

Area of a circle is given by

A = pi r^2

We are given the diameter.  We need to find the radius

d= 2r

15.8 = 2r

Divide by 2

7.9 =r

Now we can find the area

A = pi * (7.9)^2

A = pi *62.41

Let pi = 3.14

A = (3.14) * 62.41

   = 195.9674 cm^2

We round to the nearest hundredths

A=195.97 cm^2

the answer is 62.8 cubic units

a) 0
