Answer V≈351.86
Step-by-step explanation: V=πr2h=π·42·7≈351.85838
The formula for the volume of a cylinder is V=Bh or V=πr2h .
The radius of the cylinder is 4 cm and the height is 7 cm.
Substitute 4 for r and 7 for h in the formula V=πr2h .
V= pie (4)² (7)
v= pie ( 14) (49)
The answer to the question is 64°
x° + 26°= 90°
x° = 64°
Answer:

Step-by-step explanation:
Standard equation of a line is y = mx + b, where m is the slope.
Given line y = - 3x + 78, slope, m₁ = -3
<em><u>To find the line perpendicular to the given line.</u></em>
The lines are perpendicular to each other if the product of their slopes = - 1
That is,

So the slope of new line is
