Question

The width of the tiled portion is 1.5 feet. What is the area of the tiled portion of the patio, rounded to the nearest whole square foot?

Answer 1

Let's first find the area of a a semicircle with the tiled part.

Answer 2

I did that but I think I got a wrong answer. I got 56.74

Answer 3

A=(pi*r^2)/2=(25pi)/2

Answer 4

Ohh I forgot to divide by 2.

Answer 5

Now find the area of just that untiled part:
A=(pi*3.5^2)/2

Answer 6

Since if the radius is 5 and the width is 1.5 u'll subtract the width from the radius. Can you finish this off?

Answer 7

Yes I can thank you

Answer 8

and it is still dividing by 2 right?

Answer 9

yes
