Answer:

24

Step-by-step explanation:

We are given a leg and the hypotenuse, and we can put what we have into the pythagorean theorem formula:

a^2 + b^2 = c^2

7^2 + b^2 = 25^2

49 + b^2 = 625

b^2 = 576

b = 24

A Crayon is shown here.
Aleks04 [339]

The volume of the single crayon is 89.5 cm³, then the total volume of the crayons will be 2148 cm³. Then the correct option is D.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A Crayon is shown here.

There are 24 crayons in a box.

The approximate total volume of the crayons will be

Total Volume of crayons = 24 × volume of the single crayon

The crayon is the combination of the cone and the cylinder

Then the volume of the single crayon (V₁) will be

\rm V_1 = \left ( \dfrac{1}{3} \times \pi \times r^2 \times h  \right ) + \left (  \pi \times r^2 \times h  \right )\\\\\rm V_1 = \left ( \dfrac{1}{3} \times \pi \times 1.5^2 \times 2  \right ) + \left (  \pi \times 1.5^2 \times 12  \right )\\\\V_1 = 4.712 + 84.82\\\\V_1 = 89.535 \approx 89.5

Then the Total volume will be

Total volume = 24 × 89.5

Total volume = 2148 cm³

How do you solve the equation -7/8k=21
loris [4]
- \frac{7}{8} k = 21

First, simplify \frac{7}{8} k to \frac{7k}{8} / Your problem should look like: -\frac{7k}{8} = 21
Second, multiply both sides by 8. / Your problem should look like: -7k = 167
Third, divide both sides by -7. / Your problem should look like: k = \frac{168}{-7}
Fourth, simplify \frac{168}{-7} to \frac{168}{7} / Your problem should look like: k = - \frac{168}{7}
Fifth, simplify \frac{168}{7} to 24. / Your problem should look like: k = -24

Answer: k = -24
