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!!
