Question

Circumference of circle 154 cm. Find the radius of circle.​

Answer 1

Answer:

24.5

Step-by-step explanation:

circumference = 2πr

154=2πr

154/2=πr

77=πr

77=22/7×r

77×7/22=r

49/2=r

24.5=r

Answer 2

Answer:

• 24.5 cm

Step-by-step explanation:

Given

• Circumference of circle = 154 cm

To find

• Radius of circle

Solution

Circumference = 2πr

• 154 = 2πr
• 154 = 2 × 22/7 × r
• 154 = 44/7 × r
• r = 154 × 7/44
• r = 24.5

Hence, the radius is 24.5 cm
