Question

If the circumference of a circular tank is 44m. Find the diameter

Answer 1

2×3.14×r=44

6.28r=44

r=44/6.28

r=7.0

d=r

2×7.0

14

Answer 2

14 m

Solution,

Circumference of circular tank = 44m

Radius = ?

Diameter= ?

Now,

Circumference of a circle = 44

`or \: 2\pi \: r \: = 44`

`or \: 2 * 3.14 * r = 44`

`or \: 6.28r = 44`

`or \: r = (44)/(6.28)`

`r = 7.0 \: m`

Again,

Diameter = 2 radius

= 2 * 7.0

= 14 m

Hope this helps..

Good luck on your assignment..
