Question

the difference between the circumference and the diameter of a circle is 75cm find the area of circle ​

Answer 1

Answer-

a/c circumference -diameter=75cm

=> 2pi.r-2r=75cm

=> 2r (pi-1)=75cm

=> 2r (22/7-1)=2r.15/7=75cm

=> r=35/2

now

area of circle=pi.r^2=22/7 (35/2)^2=1925/2 cm^2= 962.5cm^2.

Hope it helps !!

Answer 2

Step-by-step explanation:

2πr-2r=75

2r×π=75

r=75×7/22×1/2
