Question

The radii of two circles are 8 cm and 6 cm. Find the radius of a circle having circumference equal to the sum of circumference of two circles. *
​

Answer 1

Answer:

14 cm.

Explanation:

Sum = 16pi + 12pi = 28pi

radius = 28pi/2pi = 14cm

Thanks.

Answer 2

GIVEN:-

➠ Radius of 1st circle= r*1=8 cm

➠Radius of 2nd circle=r*2=6 cm

Let the radius of required circle= r cm

According to the question,

Area of required circle= Sum of the area of both the circles

➠ Area of the first circle=π r*1^2

= π (8)^2

= π (8×8)

= 64 π

➠ Area of the second circle= π r*2^2

= π (6)^2

= π (6×6)

= 36 π
