15. The radii of two circles are 20 cm and 13 cm. Find the difference

1.	15. The radii of two circles are 20 cm and 13 cm. Find the difference between their circumference
Answer» Step-by-step explanation: Radius of 1st circle = 20 cm CIRCUMFERENCE of the circle = 2πr = 2 × 22/7 × 20 = 880/7 = 122.8 cm Radius of 2ND circle = 13 cm Circumference of the circle = 2 πr = 2 × 22/7 × 13 = 572/7 = 81.7 ∴ Difference of circumference of TWO CIRCLES = 122.8 – 81.7 cm = 41.1 cm follow me ✌️❤️ this is done✌️❤️

Answer»

Step-by-step explanation:

Radius of 1st circle = 20 cm

CIRCUMFERENCE of the circle = 2πr

= 2 × 22/7 × 20

= 880/7 = 122.8 cm

Radius of 2ND circle = 13 cm

Circumference of the circle = 2 πr

= 2 × 22/7 × 13 = 572/7 = 81.7

∴ Difference of circumference of TWO CIRCLES

= 122.8 – 81.7 cm = 41.1 cm
