Question

5. The diameter of the base of a solid hemisphere is x unit, then the area
of the whole surface is​

Answer 1

We know that the surface area of a hemisphere is 3πr².

Given diameter = x unit

Radius = $\dfrac{diameter}{2}$

$\Rightarrow \dfrac{x}{2}$

Putting the value of the radius in the formula = $3πx^{2}$

let the value of π be $\dfrac{22}{7}$

So ,the answer in terms of x is

$3× \dfrac{22}{7} x^{2}$

$\dfrac{66}{7}x^{2}$

Answer 2
