​

Answer 1

Answer:

$area = \pi \: d$

$area = \frac{22}{7} \times 70$

$area = 220 {cm}^{2}$

hope it helps!

Answer 2

GIVEN :-

• Diameter of Circle = 70 cm

TO FIND :-

• Area of Circle

SOLUTION :-

⇒ Diameter of circle (D) = 70 cm

⇒Now, we have to find radius of the circle

⇒ By applying formula :

$\pink \rightarrow \:Radius = \frac{Diameter}{2}$

$\red \rightarrow \frac{70}{2} = 35$

Now, by applying area of circle formula:

$\star\fbox\purple{Area of Circle = πr \: square} \star$

$\orange \rightarrow\frac{22}{7} \times ( {35}^{2})$
