Question

find the diameter of a circle whose circumference is 176

Answer 1

Answer:

D = 56

Step-by-step explanation:

Circumference = 2πr ( r= radius)

176 = 2πr

r = 176 / 2π

r = 176×7/2×22

r = 28

Diameter = 2r

= 2× 28 = 56

Hope it helps....

Answer 2

Answer:

Diameter = 56

Step-by-step explanation:

• Circumference = 2πr
• 176 = 2πr
• 176 = 2 * 22/7 * r
• r = (176*7) / (2*22)
• r = 1232/44
• r = 28

Since, r = 28

Then, d = 28*2

= 56
