Question

Find the area of a circle with a radius of 8, . Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal.

Answer 1

Answer:

Given :-

Radius of the circle =8cm.

To FiND:-

Area of the circle =?

Formula used :-

$Area \: of \: circle = \pi \: {r}^{2}$

SoLuTiON:-

$Area \: of \: circle = \pi \: {r}^{2} \\ Area \: of \: circle = \pi {(8)}^{2} \\ Area \: of \: circle = \pi64$

$As \: \pi = 3.14$

So ,

$Area \: of \: circle = 64 \times 3.14 {cm}^{2}$

$Area \: of \: circle = 200.96 {cm}^{2}$

Therefore the area of circle is 200.96 cm ².

Answer 2

Given:

Radius of circle = 8 units

The value of π = 3.14

To find:

The area of a circle

Solution:

Area of a circle = πr²

                          = 3.14 × 8²

                          = 200.96 square units

The area of the circle is 200.96 square units.
