Answer:
226.19
Step-by-step explanation:
Vol. of cone = Bh/3 where B is the area of the base(circle) and h is the height of the cone.
r = 3 h = 3
V = = 9π
Vol. of the cylinder = Bh where B is the base(circle) and h is the height of the cylinder.
r = 3 h = 10 - 3 = 7
V = = 63π
Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19
Answer:
5 ft : 3 ft
Step-by-step explanation:
Ratios are always fractions so we can turn this to a fraction;
Then to reduce to it's lowest terms divide by a number that can divide both of them. Lets divide by 2 since it can divide the two numbers
We can still divide by 2 since it can divide both numbers =
Since no number can divide both of them at the same time the answer is OR 5 ft : 3 ft
Answer:
The correct option is B.
Step-by-step explanation:
It is given that there is a strong, negative, linear relationship between x and y. where, x is the number of consecutive hours a worker has been assembling chainsaws and y is the number of chainsaws he can produce in an hour.
He finds that 70%of the variation in chainsaws produced per hour can be explained by the regression of y on x.
The slope is -0.7, therefore option B is correct.
