ball is 108 cm. What is the surface area
of the smaller ball?
(2)

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

step-by-step explanation:

just keep asking questions until you have a better understanding.

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
