QUESTION
A spherical balloon is being deflated. The radius is decreasing at the rate of 1.7 cm/sec. How fast is the volume decreasing when r=19 cm.
A spherical balloon is being deflated. The radius is decreasing at the rate of 1.7 cm/sec.
- How fast is the volume decreasing when r=19 cm. Note that the volume of a sphere is V=4/3(pi)r^3 where r is the radius of the sphere.
- How fast is the surface area decreasing when r=19 cm. Note that the surface area of a sphere is A=4(pi)r^2 where r is the radius of the sphere.
