Answer:
254 cubic feet.
Step-by-step explanation:
It is given that the a cylindrical tank is 6 feet across and 9 feet deep. It means
Diameter of cylinder = 6 feet
Radius of the cylinder = 6/2 = 3 feet
Height of the cylinder = 9 feet
The volume of a cylinder is

where, r is radius and h is height of the cylinder.
Substitute r=3 and h=9 in the above formula.



We need to find the maximum number of cubic feet. So approx the value to a whole number.

Therefore, the maximum number of cubic feet of paint the tank will hold is 254 cubic feet.
Answer:
Angle b is 63
Angle f is 59
Step-by-step explanation:
Answer:
∠x = 72°
Step-by-step explanation:
since two sides are equal, their opposite angles are equal.
Then the upper angle is also equal to 54°.
All triangle angles add up to 180°.
∠x = 180 - 54 - 54 = 72°
Answer:
SSS
Step-by-step explanation:
Given that the sides are equal and no angles are given
Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
