Find the area of the curved surface of a cone whose base radius is 6cm and whose height is 8cm. (take \(\pi\) = \(\frac{22}{7}\))
A
188.57cm2
B
1320cm2
C
188cm2
D
188.08cm2
E
10cm2
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
S = curved surface area = \(\pi\)rL
= \(\frac{22}{7}\) x 6 x 10
= 188.57cm2
