Answer 1

multiply each number by 3.14

Answer 2

so 1 times 3.14+ 2 times 3.14 + 3 times 3.14

Answer 3

u should get 18.84

Answer 4

next u want to round it to the nearest numberr

Answer 5

so choose 18 or 19

Answer 6

one of them is the correct answer that is close to 18.84

Answer 7

It is asking for how much snow, so you need to calculate the volume of each sphere.

Volume of a sphere = (4/3)(pi)r^3

They give you the diameter of each snowball, so divide diameter /2 for each sphere to get r

Then calculate V for each sphere

Then add the results

Answer 8

Did i not do the first part?

Answer 9

The question is asking how much snow is needed. Therefore you need volume.

Multiplying diameter * pi gives circumference not volume.

Answer 10

oh okay i see.
