Answer
Option C is correct.
Area of the circle = 56.25pi
Step-by-step explanation
The circumference of a circle is given as
Circumference = 2πr
where
π = pi
r = radius = ?
Circumference = 15pi
Circumference = 2πr
15pi = 2 (pi) (r)
15 = 2r
We can rewrite this as
2r = 15
Divide both sides by 2
(2r/2) = (15/2)
r = 7.5 cm
The area of a circle is given as
Area = πr²
Area = (pi) (7.5)²
Area = (pi) (56.25)
Area = 56.25 cm²
Hope this Helps!!!
