Answer:
The radius of the cylinder is 2.52 cm.
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and height h is
V = πr²h. We can solve this for r² by dividing both sides of the equation by πh:
r² = V / (πh)
Then the desired radius is found by taking the square root of this.
r = √{V / [πh]}
200 cm^2
Here, r² = ------------------- = 6.37 cm^2
3.14(10 cm)
and so r = √6.37 cm^2 = 2.52 cm
The radius of the cylinder is 2.52 cm.
Answer:
d-19
Step-by-step explanation:
When d=0, your position is -19 meters east of the stop sign. When you walk d meters to the east, your distance east of the sign becomes ...
d - 19
_____
Note that you must walk more than 19 meters for your distance east of the sign to become positive. If you walk exactly 19 meters, your distance east of the sign is zero.
Answer:
140 degrees.
Step-by-step explanation:
All circles are made up of 
. Each of the angles provided are called central angles, which means when we add them all together, we will get a total of
Notice the little red box, which indicates a 
angle. From the circle, we know the following angles:
We can write and solve an equation to solve for the missing angle, 
:
Combine like terms:
Subtract 
from both sides:
.
