Answer:
The curved surface area is 902 cm^2
The total surface area is 1,518 cm^2
Step-by-step explanation:
We can get the radius from the area of the circular base
The area of the circular base is;
A = pi * r^2
616 = pi * r^2
r^2 = 196.078
r= √196.078
r = 14 cm
The curved surface area is;
pi * r * l
= 22/7 * 14 * 20.5
A = 902 cm^2
The total surface area is the sum of the curved surface area and the area of the circular base
That will be;
902 + 616 = 1,518 cm^2
