Answer:
A. 2025pi in^2
Step-by-step explanation:
If you change a linear dimension by a factor of k, the area changes by a factor of k^2.
The radius changes by a factor of 3. The area changes by a factor of 3^2 which is 9.
9 * 225pi square inches = 2025pi square inches
Answer:
C
Step-by-step explanation:
Given the sides of cubes in the ratio a : b , then
ratio of volumes = a³ : b³
Here ratio of sides = 2 : 4 = 1 : 2 ( smaller : larger ) , so
ratio of volumes = 1³ : 2³ = 1 : 8
Then the volume of the larger cube is 8 times the volume of the smaller.
