If the radius of a solid object increases 2 times the volume of the object would increase how many times
1. Sphere 1 has surface area A1 and volume V1 and sphere 2 has surface area A2 and volume V2. If the radius of sphere 2 is 3.86 times the radius of sphere 1, what is the ratio of the areas A2/A1? 2. What is the ratio of the volumes V2/V1
6. Consider a cylinder with a surface area of 2 m2. Find the radius r and height h of such a cylinder so that the volume of the cylinder is a maximum. Given: For a cylinder, the surface area is S = 2^r2 + 2trh and the volume is V = arh (where r is the radius and h is the height of the cylinder). I (5)

QUESTION 4 Find the surface area of a cylinder with a radius of 3 and a height of 10. The surface area is TT units (Do not use pi in your answer as it is already written with the units above) QUESTION 5 Find the volume of a cone with a radius of 6 and a height of 8. The volume is IT units (Do not use pi in your answer as it is already written with the units above)...
3 As the volume of s cell Increases, what happens to its surface area )Its surface area increases at the same rate. bj its surface area grows more quickly than the volume. ) Its surface area stays the same d) its surface area grows but more slowly than the volume does
A spherical balloon is partially blown up and its surface area is measured. More air is then added, increasing the volume of the balloon. If the surface area of the balloon expands by a factor of 7.70 during this procedure, by what factor does the radius of the balloon increase?
6. The bright star Arcturus in the constellation Boötes has a surface temperature about 0.74 times that of the Sun. Its luminosity is about 170 times that of the Sun. (a) What is Arcturus’ radius compared to the radius of the Sun (in units of solar radii, ?⊙)? (b) What type of star is Arcturus (a dwarf, a giant, or a supergiant)? Explain your reasoning.
