Question

billy is creating a circular garden divided into 8 equal sections. The diameter of the garden is 12 feet. what is the area, in square feet, of one section of the garden?

Answer 1

area=πr^2

find the area then divide by 8


we know that diameter=2radius or diameter/2=radius so
12=diameter
12/2=radius=6
subsitute
area=π(6)^2
area=36π
divide 36π by 8
36π/8=18π/4=9π/2π=4.5π
area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
