Question

find the area of circular path with diameter 7 cm​

Answer 1

$\huge{\mathcal{\blue{\underline{Answer}}}}$

Radius = diameter / 2 = 7/2 cm

$area = \pi \: r {}^{2} \\ = \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} cm {}^{2} \\ = 38.5cm {}^{2}$

Answer 2

Question:- find the area of circular path with diameter 7 cm.

AnswEr:- We know that Radius = Diameter/2

So, Diameter = 7

=> Radius = 7/2

=> Area of Circle = πr²

(π = 22/2)

=> 22/7 × 7/2 × 7/2

=> 38.5cm²
