Question

type the correct answer in each box. complete the statement about these similar cylinders. the circumference of the base of figure 2 is $pi$ inches, and the area of the base of figure 2 is $pi$ square inches. (hint: the circumference of a circle = 2$pi$r and the area of a circle = $pi$r$^{2}$, where r is the radius.) figure 1 figure 2 reset next

Explanation:

Step1: Find radius of base of Figure 2

The radius of the base of Figure 2 is 1 inch (from the figure).

Step2: Calculate circumference of base of Figure 2

Use the formula $C = 2\pi r$. Substitute $r = 1$ into the formula, so $C=2\pi\times1 = 2\pi$ inches.

Step3: Calculate area of base of Figure 2

Use the formula $A=\pi r^{2}$. Substitute $r = 1$ into the formula, so $A=\pi\times1^{2}=\pi$ square - inches.

Answer:

$2\pi$; $\pi$
