QUESTION :-
Find the surface area of a sphere of radius 14cm?

For Moderators and Stars!​

Answer 1

Given:-

• Radius of a sphere is 14 cm.

⠀

To find:-

• Surface area of a sphere.

⠀

Solution:-

★ In this question we have given the radius of a sphere. We have to find out the surface area of a sphere. Let's do it.

⠀

Here,

• Radius = 14 cm

⠀

According to the question,

⠀

⇢ S.A = 4πr²

⇢ S.A = [4 × 22/7 × (14)²]

⇢ S.A = (4 × 44 × 14)

⇢ S.A = 2464 cm²

⠀

Hence,

• The surface area of a sphere is 2464 cm².

Answer 2

Answer:

The surface area of a sphere is 2464cm².

Step-by-step explanation:

Consider the provided information.

Here in this question we are provided that, the radius of a sphere (r) is 14cm.

And, we need to find out the surface area of sphere.

We know that,

Surface area of sphere = 4πr².

Here, the value of π is 22/7 and 3.14 and r is the radius of a sphere.

Here we will take 22/7 for π.

By using the formula and substituting all the given values in the formula, we get:

$= 4 \times \dfrac{22}{7} \times (14)^2$

$= 4 \times \dfrac{22}{7} \times 14 \times 14$

$= 4 \times 22 \times 2 \times 14$

$= 88 \times 2 \times 14$

$= 176 \times 14$

$= 2464$

Hence, the surface area of a sphere is 2464cm².

#Some formula related to it:

• Volume of sphere = 4/3πr³
• Surface area of sphere = 4πr²
• Volume of hemisphere = ⅔ πr³
• C.S.A of hemisphere = 2πr²
• T.S.A of hemisphere = 3πr²
