Question

the total surface area of a solid hemisphere is75times the area of a circle whose diameter is 6cm​

Answer 1

Answer:

2206.62 cm²

Explanation:

given : diameter of circle = 6cm

therefore, radius = 3 cm.

area of the circle = πr²

=>22/7 × 3² = 198/7

=> 28.2857 (approx) = 28.29cm² ( approx )

therefore, Total surface area of the solid hemisphere

=> (78 × 28.29)cm² = 2206.62 cm²

hope this helped !!

thanks !!
