Answer:
V = 1206.3 
Step-by-step explanation:
This shape is made up of a cylinder on the bottom and a cone on the top. We'll find the volumes of these shapes separately and then add them together.
Volume of a cylinder = area (of the base) x height
Substitute in the formula for the area of a circle.
V(cylinder) = 
x h
Substitute in the values for the radius (8) and height (4)
V(cylinder) = x 
x 4
Evaluate using a calculator
V(cylinder) = 804.2477
To the nearest tenth, V(cylinder) = 804.2
Volume of a cone = 
. This is the area of the circular part of the cone (
), multiplied by the height from the point to the base, all divided by 3.
Substitute in the values for the radius of the circle (8) and the height (6)
V(cone) = 
(On the top it's x x 6)
Evaluate using a calculator
V(cone) = 402.1239
To the nearest tenth, V(cone) = 402.1
Total volume = V(cylinder) + V(cone)
= 804.2 + 402.1
= 1206.3
Examples :
(-2)^3 = (-2)(-2)(-2) = - 8
(-3)^4 = (-3)(-3)(-3)(-3) = 81
(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1
** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative
** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25
Answer:
He needs 7 buckets of cement, and 28 buckets of sane.
Step-by-step explanation:
cement : sand
1:4 = 5
35/5 = 7
7*1=7 . Cement
7*4=28 . Sand
lines a and d are parallel and lines b and c are parallel
