Answer:
527.6 cubic inches
Step-by-step explanation:
The volume of a cylinder is represented by the formula 
, where r represents the radius of the base and h represents the height.
In this question, the diameter is given as 9 inches. Since the radius is half the diameter, the radius will be 4.5 inches.
Substituting in the values and solving, we get:
The Volume will be 527.6 cubic inches
Answer:
She ate 8 donuts the first day, 14 on the second, 20 on the third, 26 on the fourth, and 32 on the fifth day
Step-by-step explanation:
Over the course of 5 days, she ate 100 donuts, each day eating 6 more than the day before. Let n be the number of donuts she ate on the first day, then she ate...
Day 1: n donuts
Day 2: n + 6 donuts
Day 3: n + 12 donuts
Day 4: n + 18 donuts
Day 5: n + 24 donuts
Add the days together and get the equation...
n + (n + 6) + (n + 12) + (n + 18) + (n + 24) = 100
Now combine like terms and solve for n...
5n + 60 = 100
5n = 40
n = 8
She ate 8 donuts the first day, 14 on the second, 20 on the third, 26 on the fourth, and 32 on the fifth day
6 x 6 = 36
6 x -6x = -36x
324/-36
x=-9
