When making a snowman out of three snow spheres, let’s have the ratio of the diameter of each of the three spheres be 1:2:3. If the diameter of the smallest sphere (the top) is 18 inches, what is the diameter, in feet, of the largest sphere (the bottom) of the snowman? Express your answer as a decimal to the nearest tenth.
________________________________________
What is volume of the middle sphere, in cubic inches? Express your answer in terms of pi. The formula for the volume of a sphere is (4/3)(pi)r3.
________________________________________
What is the ratio of the volume of the smallest sphere to the volume of the middle sphere? Express your answer in the form a:b.
________________________________________
Assuming that our three spheres are placed one on top of the other with no "smushing" or "denting" of the spheres, how many feet tall is our snowman?



Can you help me out, or you don't have to tell me the answer, just can you tell me what steps I need to do to find the answer?

the relationship between celcius and fahrenheit degrees for measuring temperature is linear. find an equation relating celcius and fahrenheit...

0 celcius = 32 fahrenheit
100 celcius = 212 fahrenhiet

use the equation to find the celcius measure of 70 degrees

13 + (-12) - (-5)

Wouldn't the 13 be a positive number? If so; 13 and -12 are different- thus, you would subtract.

13-12= -1
-1 - (-5) : the same... so you would add = -6

But supposedly the answer is 30. What am I doing wrong?
Explain please

Thank you
