Given that the ball has a thickness of 1 cm and the radius at the outside is 5 cm, thus the radius from inside is 5 - 1 = 4cm.
The <span>approximate volume of rubber used to make the ball is given by the volume of the ball at the outside surface minus the volume of the ball at the inside surface.

Step-by-step explanation:
Answer:
for #1 its the 1st and 4th box
for # 2 it's 13.5 and 20.25
Step-by-step explanation:
1st box - 10 ÷ 5 = 2 and 25 ÷ 5 = 5
4th box - 10 x 2 = 20 and 25 x 2 = 50
you have to make sure that you do the same thing for both sides of the equation
6 x 2.25 = 13.5
9 x 2.25 = 20.25
Dilation is an enlarging or shrinking of a math figure using a specific scale factor
multiply your numbers by that given scale factor to give you your answer of option 2

Answer:
y(-4) = 5
y'(-4) = -7
Step-by-step explanation:
Hi!
Since the tangent line T and the curve y must coincide at x=-4
y(-4) = T(-4) = 5
On the other hand, the derivative of the curve evaluated at -4 y'(x=-4) must be the slope of the tangent line. Which inspecting the tangent line T(x) is -7
That is:
y'(-4) = -7
