Question

What is the diameter of a circle if its circumference is 75.46​

Answer 1

Circumference of a circle = 75.46cm

2πr = 7546

100

πr = 7546

100×2

=> r = 7546×7

100×2×22

=> r = 1200.5

100

=> r = 12.005cm

Diameter = 2×r

= 2×12.005

= 24.015 cm

I assumed that the unit of circumference was cm

Answer 2

Answer:

24.01

• Step-by-step explanation:

Circumference=75.46

Diameter=?

We know,

C=2πr

75.46=2x22/7xr

75.46=44r/7

44r=528.22

r=528.22/44

.:.r=12.005

d=rx2

 =12.005x2

 =24.01
