Katarina [22]

Answer:

1.214 or 1\frac{3}{14} or \frac{17}{14}

Step-by-step explanation:

To solve this equation, first you need to the variable term isolated. You do this by adding 10 to each side. Your equation will now look like

17c = 14

Next, you will divide both sides by the 17.

Your equation now is solved, and above, I put ther three different forms for your answer: decimal, mixed number, and improper fraction.

alexandr402 [8]

Answer:

1779.33 mm³

Step-by-step explanation:

We are given a candle in a form of a cylinder and a cone

Dimensions;

Common radius is 5 mm

Height of the cylinder is 20 mm

Height of the cone is 8 mm

We are required to determine the amount that it can hold.

To answer the question we are going to determine its volume

Cylinder;

Volume of a cylinder is given by;

V = πr²H

Taking π to be 3.14

Then ;

Volume of cylinder = 3.14 × 5mm² × 20 mm

                                = 1570 mm³

Cone

Volume of a cone is given by;

V = 1/3πr²H

That is;

Volume =1/3 × 3.14 × 5mm² × 8 mm

            = 209.33 mm³

Therefore;

Volume of the solid = 1570 mm³ + 209.33 mm³

                                 = 1779.33 mm³

Thus, the volume of the solid is 1779.33 mm³
