ICE Princess25 [194]

Answer:

87.28 cubic inches

Step-by-step explanation:

Leigh wants to fill the conical candle wax mold completely with candle wax.

We have to calculate the volume of the cone by the formula :

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

Here, V = volume

r = radius = 2.1 inches

h = height = 18.9 inches

By substituting these values given, into the formula

$V=\pi (2.1)^2(\frac{18.9}{3})$

= (27.783)π

= 87.28 inch³

Conical mold can hold 87.28 inch³ candle wax.

Express tan M as a fraction in simplest terms.<br> Help please

kirza4 [7]

Answer:

tan M = $\frac{24}{7}$

Step-by-step explanation:

To obtain tan M we require to find KL

Using Pythagoras' identity in the right triangle.

KL² + LM² = KM²

KL² + 7² = 25²

KL² + 49 = 625 ( subtract 49 from both sides )

KL² = 576 ( take square root of both sides )

KL = $\sqrt{576}$ = 24

Then

tan M = $\frac{opposite}{adjacent}$ = $\frac{KL}{LM}$ = $\frac{24}{7}$
