Question

. Find the radius of a circle whose circumference is 176 cm.
- Find the diameter of a wheel whose circumference is 264 cm.

Can anyone explain this with proper solution...​

Answer 1

Answer:

Radius:176/(2*pier) (do the ans by yourself)

Diameter:264/pier (do the ans by yourself)

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Let the radius of the circle = r

Perimeter ( P ) = 2πr

Perimeter = 176 cm  [ given ]

2πr = 176 cm

2 × ( 22/7 ) × r = 176

r = (176) × ( 7/22) × ( 1/2)

r = ( 176 × 7 × 1 ) / ( 22 × 2 )

After cancellation

r = 28 cm

Therefore,

Radius of the circle = r = 28cm

-------------------------------------------------------------------

Let the radius of the wheel be r

Then its circumference = 2πr = 264 cm.

So,2πr =264 cm

So, r =(264/2 × 7 /22) cm

=( 84/2 ) cm

=42 cm

Radius = 42 cm.

And,

Diameter = (42×2)cm

=84 cm

So , diameter of the wheel whose circumference is 264 cm = 84 cm
