Question

find the area of a circle whose radius is 4.9 ​

Answer 1

Answer:

by using πr²

Step-by-step explanation:

75.39 sq units

Answer 2

Given -

Radius - 4.9 unit

To find -.

Area of circle.

Solution -

As we know that,

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

Put the given values in the formula we get

Area of circle $= \pi \times {4.9}^{2}$

Square means multiply the given values itself.

${4.9}^{2} = 24.01$

So,

Area of circle $= \pi \times 24.01$

Area of circle $3.14 \times 24.01$

Area of circle $= 75.39$

Hence ,

Area of circle is 75.39 sq. unit.
