Question

Find the diameter of the circle whose circumference is 230 m.​

Answer 1

Answer:

d=73.2

Step-by-step explanation:

Circumference of circle=230m

2πr=230

2×22/7×r=230

r=230×1/2×7/22

r=(115×7)/22

r=805/22

r=36.59

r=36.6cm

d=2r=2(36.6)=73.2cm

Therefore, the diameter of the circle is 73.2cm.

Answer 2

Answer: it’s a pleasure to help you friend !!!

Step-by-step explanation:

GIVEN :

Diameter = 230 m

TO FIND :

The circumference of the circle.

SOLUTION :

We know that,

Radius = diameter / 2

So, r = 230 / 2 = 115 m

Now,

CIRCUMFERENCE OF A CIRCLE = 2πr

So, = 2 × 3.14 × 230

= 3.14 × 460

= 1444.4 m

Therefore, the circumference of the circle = 1444.4 m.

Hope it’s useful friend,

Good luck and have a great day !!

Stay safe and happy...
