How do you solve literal equations
Mnenie [13.5K]
<span>See examples before for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2. my own words didnt get off google im a teacher</span>

Which solid has a greater volume
Triss [41]

Answer:

The volume of cylinder and the volume of a cone, have equal volume measurements. So, the answer is C).

Step-by-step explanation:

Cylinder:

-Use the formula for the volume of a cylinder. Use both the radius and height for the formula in order to solve and get the volume:

V = \pi r^2 h

V = \pi 2^2 6

-Solve:

V = \pi 2^2 6

V = \pi \times 2^2 \times 6

V = \pi \times 4 \times 6

V = \pi \times 24

V = 24\pi \approx 75.39

--------------------------------------------------------------------------------------------------------

Cone:

-Use the formula for the volume of a cone and the radius and height for the formula and solve the formula to get the volume:

V = \frac{1}{3} \pi r^2h

V = \frac{1}{3} \pi 3^28

-Solve:

V = \frac{1}{3} \pi 3^28

V = \frac{1}{3} \times \pi \times 3^2 \times 8

V = \frac{1}{3} \times \pi \times 9 \times 8

V = \frac{1}{3} \times \pi \times 72

V = \frac{1}{3} \pi \times 72

V = 24\pi \approx 75.39

-So, according to the volume of a cylinder and the volume of a cone, They both have the same volume.

Cylinder: 75.39 ft^3

Cone: 75.39 ft^3
