Question

The diameter of a wooden hemisphere is 16cm. Find its surface area?​

Answer 1

Answer:

surface area=2πr

= 2×.22/7× 8

= 44/7×8

=0.9056677018633

Answer 2

Given,

The diameter of a wooden hemisphere = cm.

To Find,

The surface area of the hemisphere.

Solution,

Given that,

The hemisphere-shaped wooden has a diameter of 16cm.

The hemisphere wooden block's surface area.

2$\pi r^{2}$ is the formula to use.

Area = 2$\pi r^{2}$

$\pi =$ 3.14 or $\frac{22}{7}$

And the radi r = $\frac{16}{2}$.

r = 8cm

Therefore surface area  = 2 × $\frac{22}{7}$ × 8 × 8.

A =  402.3cm².

Hence, 402.3cm² is the surface area of the hemisphere wooden.
