Question

the circumference of a circle exceeds the diameter by 120cm. find the diameter and the circumference

Answer 1

Answer:

We know that r = d/2 (or) d = 2r. Given circumference of a circle exceeds diameter by 120cm. = 28. Diameter = 2 * r = 56.

Answer 2

Answer:

The circumference is 176 cm.

Step-by-step explanation:

Let the diameter of the circle be= x

Then, the circumference of the circle will be= x+120

ATQ

πx=x+120

22x/7=x+120

22x/7-x=120

15x/7=120

X=120*7/15

X=840/15

X=56

So, the diameter is 56 cm

Now, the circumference= 2πr

R=D/2 =56/2 =28

2πr= 2*3.14*28 =176cm

Hope it helps...
