Question

find the surface area of sphere of radius 2cm​

Answer 1

Answer:

Sphere

Solve for surface area

A≈50.27cm²

r Radius

2

cm

Answer 2

Answer:

Hence, area of sphere will be 50.3 Sq. cm

Step-by-step explanation:

In context to question asked,

We have to determine the surface area of the sphere.

As per question,

We have,

Radius of sphere = 2 cm

As we know that,

Sphere is a three dimensional figure.

The surface area of sphere can be determined by using formula,

$Area = 4 \Pi r^2$

So, for determining the surface area we will put the value of r given in the question in above formula,

Thus we will get,

$Area = 4 \Pi r^2\\=> 4 \times \frac{22}{7} \times 2 \times 2\\=>\frac{4 \times 22 \times 4}{7}\\=>\frac{352}{7} = 50.2857 \approx 50.3\:cm^2$
