Question

10] The square with side 19.25cm made
i ured to make a circle. Find the
a) radius b) diameter
c)Circumference d)area of a circle
​

Answer 1

Answer:

Circumference = 19.25 (given)

2 π r² = 19.25

2 * 22/7 *r² = 19.25

r² = 19.25 * 7 / 2*22

r² = 539/176

r² = 3.0625

r = ✓3.0625

r = 1.75

1) Therefore , Radius = 1.75cm

2) Diameter 2*r

= 2*1.75

= 3.5 cm

3)Circference = 2πr² = 2*22/7* (1.75)²

= 19.25 cm

4) Area = πr² = 22/7 * (1.75)²

= 67.375/7

= 9.625

Hope this helps u!!
