Answer:
Step-by-step explanation:
First you have to find the area of the full circle.
Area of circle:
A = pi radius^2.
A = 4 x 4
A = 16 pi squared
Area of rectangle:
3 x 3 = 9 cm
Now you have to subtract.
16 - 9 = 7 pi spuared
or if you answer wants to go a step farther:
21.98 squared
Answer: So to cover the patio it would take 255 whole tiles. 254.469 if you want to be exact.
Step-by-step explanation:
When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A=
so we plug in our known variables...
we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.
r=9
A=
A=
81
A=254.469
