Those who will answer me I will mark him/her the brainliest. Promise.
Find the area of the circular region of radius:
i) 7cm
(ii) 14cm
(iii) 9.8cm​

Answer 1

Answer:

154 sq.cm

616 sq.cm

301.84 sq.cm

Step-by-step explanation:

Area of circle = π$r^{2}$

When Radius = 7 Then area is = 22/7 * 7 * 7  = 154 sq.cm

When Radius = 14 Then area is = 22/7 * 14 * 14 = 616 sq.cm

When Radius = 9.8 Then area is = 22/7 * 9.8 * 9.8 = 301.84sq.cm

Answer 2

area of circle = πr²

(I) 22/7 * 7*7

154 cm²

(II) 22/7 * 14 * 14

616 cm²

(III) 22/7 * 9.8 * 9.8

301.84 cm²
