Question

Find the area of the circle of R-49 m
(take π = 22/7) ​

Answer 1

Answer :

Area of circle is 4312 m²

Given :

Radius = 49m

To find :

Area of circle

Solution :

As we know that,

Area of circle = πr²

Where , r is radius

》Area of circle = πr²

》22/7 × 49 × 49

》22 × 4 × 49

》4312m²

Hence, Area of circle is 4312 m²

Verification :

As we know that,

Area of circle = πr²

》4312 = 22/7 × 49 × 49

》4312 = 22 × 4 × 49

》4312 = 4312

Hence, Verified

More Explanation :

Circumference of circle = 2πr

Diameter of circle = 2r

Answer 2

Answer:

= 7546 $mm^{2}$

Step-by-step explanation:

(b) Area of a circle = $\pi r^{2}$

                             =  $\frac{22}{7}$ X $49^{2}$ mm

                            =  $\frac{22}{7}$ X 49 X 49

                        > 7 and 49 can be reduced

                            = 22 X 7 X 49

                            = 154 X 49

                            = 7546 $mm^{2}$
