Answer:
8
Step-by-step explanation:
2(5x2-4+2)=2(10-4+2)=2x4=8
Answer:
c)A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
Step-by-step explanation:
A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
The volume of a cylinder is given by V=Bh or V=πr²h
where B is the area of the base and h is the height of the cylinder.
V=πr²h-------equation1
V= π(w³ +2w² )--------- equation2
Comparing equation 1 and equation 2
πr²h=π(w³ +2w² )
r²h=(w³ +2w² )
r²h= w²(w +2 )
Taking w² common leaves w+2 which gives the height or length of the cylinder.
Therefore radius = width and height = length which gives the volume of the cylinder.
Answer:
n = 15
Step-by-step explanation:
This is a right triangle, and so the Pythagorean Theorem applies:
x^2 + 8^2 = 17^2
Solving for x^2: 17^2 - 8^2 = 289 - 64 = 225, and so x = 15.
n = 15
