Answer:
The correct answer is option C. 119π cm²
Explanation:
Points to remember
Surface area of cone = πrl + πr²
Where r is the base radius and l is the lateral edge
To find the surface area of given cone
Here r = 7 cm and l = 10 cm
Surface area = πrl + π r² =( π * 7 * 10) + (π *7²)
= 70 π + 49π
= 119π cm²
Therefore correct answer is option C. 119π cm²
