The second hand of the clock is 3.7 cm long. Find the linear speed of the tip of the second hand as it's passes around the clock face.
O 0.00646 cm per sec
O 172.03 cm per sec
O 0.387 cm per sec
2.87 cm per sec

I'd look it up would probably work if not see if someone else might be able to help you out with this

answer: ok

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
