Question

the circumference of a circle is hundred centimetre find the area and diameter​

Answer 1

Answer:

The diameter is 31.84cm. The area of circle is 795.82$cm^{2}$...

Step-by-step explanation:

Circumference = 100cm

i.e dπ = 100cm

d x 3.14 = 100cm

d = 100/3.14

d = 31.84cm

Therefore,

r = 31.84/2

r = 15.92

Area of Circle = π$r^{2}$

                       = 3.14 x 15.92 x 15.92

                       = 795.82$cm^{2}$
