# Calculate the total surface area of a solid cone of slant height 15cm and base radius 8...

### Question

Calculate the total surface area of a solid cone of slant height 15cm and base radius 8cm in terms of π

A) 64πcm2

B) 12Oπcm2

C) 184πcm2

D) 200πcm2

E) 32Oπcm2

### Explanation:

Total surface are of a cone
= πr(r + l)
= π x 8 (8 + 150)
= 184πcm2

## Dicussion (1)

• Total surface are of a cone
= πr(r + l)
= π x 8 (8 + 150)
= 184πcm2
