$\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}$

$\implies$ Here the question has given us that the radius of a sphere that is 6 cm. Now, the question has asked us to find out the surface area of the given sphere.

✭ HOW TO DO:-

◉ Here to find out the surface area we simply need to apply the formula of surface area of sphere that is 4πr². Here we will assume the π as 3.14 as it is given in the question. After that we have to solve it by applying the values and the result will be the surface area.

ANSWER:-

↣The surface area of the given sphere is 452.16 cm².

GIVEN:-

➲ Radius of sphere = 6 cm

TO FIND:-

➾ Surface area of sphere = ?

FORMULA:-

☞ Surface area of sphere = 4πr²

SOLVING BY APPLYING THE FORMULA:-

➲ Radius of sphere = 6 cm

☞ Surface area of sphere = 4πr²

• Finding the surface area:-

➤ Surface area = 4 × 3.14 × 6 cm²

➤ Surface area = 4 × 3.14 × 6 cm × 6 cm

➤ Surface area = 4 × 3.14 × 36 cm²

➤ Surface area = 12.56 × 36 cm²

➤ Surface area = 12.56 × 36 = 452.16 cm²

➤ Surface area = 452.16 cm²

Thus, we got the answer. The surface area of the given sphere is 452.16 cm².
