Question

total area of a solid semisphere is 147 CM square find the base radius of the sami-sphere​

Answer 1

Answer:

Radius= 2.28 cm

Step-by-step explanation:

Answer 2

surface area of semisphere is 2πr^2.

largest circle in a semisphere is it's base.

radius of the largest circle is √SA/2π^2

= √147/(2×22/7)^2

=√147/(2×22/7×22/7)

=√147/ 19.75510

=12.1345/19.75510

= 1.613 cm approx.

but if we take π3.14.

so it will be 1.601.
