Question

the ratio of surface areas of figure 11 to figure 12 is 25:16. if the radius of figure 11 is 9 cm, what is the radius of figure 12?

Answer 1

Answer:

Radius of Figure 12: 5.76

Step-by-step explanation:

To find the radius of figure 12, set up a proportion. (r = radius of figure 12)

25/16 = 9/r          Cross multiply.

25r = 144             Divide 25 on both sides.

r = 5.76

The radius of figure 12 is 5.76 units.
