hey mate your answer plz mark as brainlist
total surface area
If this is what is meant by the surface area of a hemisphere then 2 π r2 = 1062. Solve for r. If you have a hemispherical object then it has a base which is a circle of radius r.

TSA of hemisphere=3πr^2
Given: 3πr^2 = 1848
r^2 = 1848*7/22*3
r^2 = 28*7
r= √28*7
r= 2*7
r= 14 cm
Therefore, diameter = 2*14
= 28 cm
