Can someone tell me the answer to this question and show me the work #11

Step-by-step explanation:

You are told that the diameter of a penny is 3/4 of an inch. The decimal equivalent is 0.75 inches.

r = d/2

r = 0.75/2 = 0.375 inches.

Area = pi r^2

pi = 22/7

r = 0.375

Area = 22/7 * 0.375^2

Area = 22 * 0.375^2/7

Area = 3.094 / 7

Area = 0.44196

If you retain this in fractions then the answer is 99/224

Area = 22 / 7 * 3/8 * 3/8

Area = 22/7 * 9/64

Area = 198 / 448     Both can be divided by 2

Area = 99 / 224

I did it the top way because I think it is the most common way to solve this question. Your teacher may not agree, but you should see both ways.

Area = 3.094 square inches.

Fraction = 3.
