Circle C has a center of (−3, 1) and a radius of 4. Circle E has a center of (4, 9) and a radius of 3. Prove that the two circles are similar.

Question

Idk what you need to state to prove that all circles are similar, but they all have the same ratio of radius to circumference (obviously).

Google "are all circles similar" to find plenty of results.

The volume of a cylinder is 81 ft3. The volume of a cube is 42 ft3. What is the difference between the volume of a cone that fits exactly inside the cylinder and the volume of a pyramid that fits exactly inside the cube? Provide an explanation for your answer to receive full credit.

i know this is late but 
volume of cone (1/3)*(volume of cylinder)
(1/3)*93ft^3)
(31ft^3)
volume of pyramid (1/3)*(volume of cube)
(1/3)*(48ft^3)
(16ft^3)
31-16 = 15 
answer = 15 ft^3
