Answer:
A = 78.5 in ^2
Step-by-step explanation:
Area of a circle = pi * r^2
The radius is d/2
r= 10/2
r =5
A = pi * r^2
Substitute r=5
A = pi *(5)^2
A = 25 pi
We know that pi is approximated by 3.14
A = 25 (3.14)
A = 78.5 in ^2
When you add a zero to the problem, it shows you are now multiplying in the double-digits. Let's say you are multiplying 12x12. First you cover up the one then multiply them. Then cover up the two and you have 10. When you multiply them, it ends in a zero. Don't think of it as adding a zero but adding to products.
