Question

The total surface area of a hemi-sphere is how much times the square of its radius​

Answer 1

Answer:

hey mate here is your answer

The surface area of a hemisphere - Math Central If you have a hemispherical object then it has a base which is a circle of radius r. The area of a circle of radius r is π r2 and thus if the hemisphere is meant to include the base then the surface area is 2 π r2 + π r2 = 3 π r2. Hence in this case 3 π r2 = 1062. Solve for r.

hope it's helpful for you.

Answer 2

Total surface are of hemisphere is $\dfrac{66}{7}$ times of square of its radius.

Step-by-step explanation:

Since we have given that

Total surface area of hemisphere = $3\pi r^2$

And the square of radius is expressed as

$r^2$

So, Total surface area = $3\times \dfrac{22}{7}$ times of square of its radius.

Total surface area = $\dfrac{66}{7}$ times of square of its radius.

Hence, total surface are of hemisphere is $\dfrac{66}{7}$ times of square of its radius.
