one link in a chain was made from a cylinder that has a radius of 3 cm and a height of 25 cm. how much plastic coating would be needed to coat the surface of the chain link? use 3.14 for π.
a: 251.2 cm2
b: 314 cm2
c: 345.4 cm2
d: 471 cm2

d. 471 cm²

step-by-step explanation:

the surface area of a cylinder (without the ends) is:

a = 2π r h

given r = 3 and h = 25:

a = 2 (3.14) (3) (25)

a = 471

the surface area is 471 cm².

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )
