Answer:

D. 8

Step-by-step explanation:

DC = AC = x is the radius

<u>Using the Pythagorean theorem, find x:</u>

(x + 9)² - x² = 15²
x² + 18x + 81 - x² = 225
18x = 225 - 81
18x = 144
x = 144/18
x = 8

Find the volume of a cone of radius 49cm and height 10cm

den301095 [7]

Answer:

Step-by-step explanation:

Given,

Radius ( r ) = 49 cm

Height (h) = 10 cm

Volume of cone=?

Now,

Applying the formula to find the volume of cone:

$\pi \: {r}^{2} \frac{h}{3}$

Plugging the values,

$\frac{22}{7} \times {49}^{2} \times \frac{10}{3}$

$\frac{22}{7} \times 2401 \times \frac{10}{3}$

Calculate

$25153.34 \: {cm}^{3}$

Hope this helps...

Good luck on your assignment..
