Heya Friend,
Here is your answer.

☆ Area of circle = Area (circle with r = 24 cm) + Area of circle with r = 7 cm).
Area of circle = 2 pie r^2 + 2 pie r^2
= 2×22/7×556 + 2× 22/7 × 49.
= 3975
☆ Diameter =
To find diameter, first, we wanna find raduis and then double it.
2 pie r^2 = 3975
r^2 = 3975/2 pie = 6240.75
r = 78.99
☆ Therefore, diameter = 157.99 cm
Hope it helps..!!
