Answer:
63pi
Step-by-step explanation:
the formula for the volume of a cylinder is pi r^2 h
r=radius
h=height
3=r
7=h
pi((3)^2)7
63pi units^3
Hope that helps :)
Answer: 6 and -1/6
Step-by-step explanation:
solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.
Answer:
3
Step-by-step explanation:
The tenths is the closest to the ones places.There is more than 4 so we can add 1 to the whole number and take off the extras,and there you have it!
So you want to cross multiply. then it would be 3x=25 then divide by 3 isolating x. x=25/3
<span>1) Multiply both sides of the equation by 2:
2(A)=2[1/2h(b+c)
2A=2/2h(b+c)
2A=1h(b+c)
2A=h(b+c)
2) Divide both sides of the equation by (b+c):
(2A)/(b+c)=[h(b+c)]/(b+c)
2A/(b+c)=h
h=2A/(b+c)
