Step-by-step explanation:
Given find the circumference of the circle whose area is 16 times the area of the circle with diameter 7 cm
- So d = 7 cm
- r = 7/2 = 3.5 cm
- Now let R be the radius of the resultant circle.
- Area is 16 times area of circle.
- π r^2 = 16 π (3.5)^2
- r^2 = 16 x (3.5)^2
- r = 4 x 3.5
- r = 14 cm
- So circumference = 2πr
- = 2 x 22/7 x 14
- = 88 cm
- Therefore the circumference of the circle is 88 cm
