Question

find the circumference of the circle whose area is 16 times the area of the circle with diameter 7 cm​

Answer 1

Step-by-step explanation:

given,

area=16+x

diameter=7cm

circumference=?

radius=7÷2=3.5cm

area=(pie r square)

16+x=22÷7×(3.5)×(3.5)

16+x=3.14×12.25

16+x=38.465

x=38.465-16

x=22.465
