Question

Andrew's bicycle has tires with a radius of 7 inches. What is the area of one of the bicycle tires, in terms of π?

Answer 1

49π

Explanation:

`r = 7\\A = ?\\A =\pi r^2\\A =\pi7^2\\A = 49\pi`

Answer 2

49π

Explanation:

The formula for the area of a circle is,

`\pi r^2`

If the radius is 7 inches we need to plug that in for r in the formula.

π(7)^2

7*7 = 49

Thus,

the area in terms of pi is 49π.

Hope this helps :)
