Answer 1

Using the given information, the height of the shorter cone is 6.81 cm

Calculating volume of a cone

From the question, we are to determine the height of the shorter cone.

First, we will calculate the volume of the first cone

Using the formula for calculating the volume of a cone,

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

Where V is the volume

r is the radius

and h is the height

From the given information,

r = 8.5 cm

h = 10 cm

Then,

$V = \frac{1}{3}\pi \times 8.5^{2}\times 10$

$V = \frac{1}{3}\pi \times 72.25\times 10$

$V = \frac{722.5}{3}\pi$ cm³

Now, for the shorter cone

r = 10.3 cm

Since the two cones have the exact same volume, we can write that

$\frac{722.5}{3}\pi= \frac{1}{3}\pi \times 10.3^{2} \times h$

$722.5= 106.09 \times h$

$h = \frac{722.5}{106.09}$

h = 6.81 cm

Hence, the height of the shorter cone is 6.81 cm.
