Answer:
The area of the circle is 314 inches
Step-by-step explanation:
Area if a circle = πr²
r = radius
r= d/2
r=20 /2
r=10 inches
Area =3.14×10²
= 3.14×100
=314 inches
To solve for this we will follow PEMDAS to arrive at the correct answer so we have the following:
Based on calculations the correct answer is A
