a) The circumference of the base of figure 1 is 5π inches.
b) The area of the base of figure 2 is 6.25π square inches.
What is circumference?
The circumference of the circle is the length of the curve traced out from the fixed point which is equidistant from the locus of the curve.
Since the cylinders are similar, you can assume that they are proportional.
The equation would be 9/5 = 4.5/x
Cross multiply and divide, and you get the radius of 2.5.
Circumference for the figure 1 will be:-
C = 2 x 2.5 = 5π
Area for the figure 2 will be:-
A = 2.5 x 2.5 = 6.25π
Therefore The circumference of the base of figure 1 is 5π inches.
The area of the base of figure 2 is 6.25π square inches.
The circumference of the base of figure 1 is 5π inches.The area of the base of figure 2 is 6.25π square inches.
