Question

11. The radii of two circles are 19 cm and 9 cm respectively. Find the radius and area of
circle which has its circumference equal to the sum of the circumferences of the
circles.​

Answer 1

Answer:

Area of circle=2464cm^2

Step-by-step explanation:

2×22/7×R=(2×22/7×r1)+2×22/7×r2

2×22/7×R=2×22/7(r1+r2)

R=r1+r2

R=19+9

R=28cm

Area of circle=22/7×R^2

=22/7×28×28

=22×4×28

=22×112

=2464cm^2

Answer 2
