Question

Find the circumference of a circle given that :-
1. Radius - 9.1 cm
2. Daimeter - 56 cm

Answer 1

Answer:

176 cm

Step-by-step explanation:

Circumference = 2πr

= 2*22/7*9.1

= 176 cm

Answer 2

$\boxed{\boxed{\huge{\red{\mathfrak{Answer}}}}}$

1] Radius = 9.1

$\implies$Circumference of a circle = 2πr

= 2 × 22/7 × 9.1

= 2 × 22 × 1.3

= 57.2cm²

2] Diameter = 56cm

$\implies$ Circumference of circle = πd

= 22/7 × 56

= 22 × 8

= 176 cm²
