2. ### find the surface area when the radius of a sphere is 5cm the function isV(r)=4*pi*r^2 where pi= 3.1416 start?

Given: area = 4*pi*r^2 r = 5cm pi = 3.1416 area = 4*3.1416*5^2 = 4*3.1416*25 = 314.16 cm^2

4. ### Find the velocity and acceleration as functions of t?

s(t) = t^3 - 3t v(t) = ds/dt = 3t^2 - 3 a(t) = dv/dt = 6t Find the acceleration after 2 s. a(2) = 6(2) = 12 meters per sec^2 Find the acceleration when the velocity is 0. v(t) = 3t^2 - 3 = 0 iff 3t^2 = 3 iff t^2 = 1 iff t = 1 [t = -1 makes no sense] a(1) = 6(1) = 6 meters...
