The formula for the area of a circle is:
A=πr²
We don't know the radius of the circle, but we do know the diameter. 14cm
The radius is half the value of the diameter:
2r=d
Lets solve for the radius
2r=14
divide both sides by 2
r=7 cm
now we can solve for the area.
A=πr²
A=π7²
A=π49
A=3.14*49
A=153.86 cm²
Answer=153.86 cm²
