She read 1/3 of a book per month. divide the amount of books by the number of months
The equation to find the volume of a cylinder is V=

×r²×h. To find r you just divide the diameter which is 10 by 2 so r is 5. Just plug everything in and solve, V=

×5²×243.84. You should get V≈19,151.15
Your answer should be 46 cm^2
7v = 2v - 20
First, subtract 2v from both sides. / Your problem should look like: 7v - 2v = -20
Second, simplify 7v - 2v to 5v. / Your problem should look like: 5v = -20
Third, divide both sides by 5. / Your problem should look like: v =
Fourth, simplify

to 4. / Your problem should look like: v = -4
Answer:
v = -4
