Answer 1

Correct Question:

A wooden toy is in the form of a hemisphere is surmounted by a right circular cone. The diameter of the base is 13cm and the height is 5cm. Find the surface area of the toy.

Answer:

$\boxed {157.14 \: cm}^{2}$

Given:

1. Diameter of the base = 13 cm.
2. Height = 5 cm.

To Find:

• Surface area of the toy.

Formula Used:

• Area of hemisphere = ${2\pi r}^{2}$

Solution:

⟹ $2 \times \frac{22}{7} \times 5 \times 5$

⟹ $\frac{44}{7} \times 25$

⟹ $\frac{44 \times 25}{7}$

⟹ $\frac{1,100}{7}$

$\huge \boxed{ { \implies157.14 \: cm}^{2} }$
