A wooden cylinder beam of length 5 meters has a radius of 210cm. the wood density is 693kg/m i) calculate the volume of the beam in cubic meters
ii) calculate the mass of the beam in kilograms.

Cylinder Volume   =   π • r² • height

Volume = PI * .210 m^2 * 5

Volume = 0.6927211801 cubic meters

Wood has a mass of 693 / cubic meter

mass = 0.6927211801 * 693 = 480.06 kilograms

Step-by-step explanation:

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.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
