.....[1]
where,
l is the length
w is the width
h is the height of the rectangle respectively.
As per the statement:
A rectangular solid has sides of 7 cm, 9 cm, and 11 cm
⇒ l = 7 cm , w = 9 cm and h = 11 cm

The radius of B is 2.5cm.
<h3>What is a circle?</h3>A circle is the locus of points equidistant from a common point which is called the center of the circle.
Analysis:
Area of circle A = π/4 = π
/4 = 225π/4
Area of circle B = π
But A = 9B
225π/4 = 9 x π
= 225/36 = 25/4
r = = 5/2 = 2.5cm
