Study the example on the right to help you complete the problem below. please help!:(

Inga [223]

Answer : The equation for 'h' is $h=\frac{2A}{b}$

Step-by-step explanation :

The given equation is:

$A=\frac{1}{2}bh$

Now we have to determine the equation for 'h'.

$A=\frac{1}{2}bh$

Multiplying the equation by 2.

$2\times A=2\times \frac{1}{2}\times bh$

on simplifying, we get:

$2\times A=bh$

Dividing the equation by 'b'.

$\frac{2\times A}{b}=\frac{bh}{b}$

$\frac{2\times A}{b}=h$

or,

$h=\frac{2A}{b}$

Therefore, the equation for 'h' is $h=\frac{2A}{b}$

Find the volume of a right circular cone that has a height of 9.1 cm and a base with a circumference of 13.3 cm. Round your answ

diamong [38]

Answer:

Volume = 42.8 cubic centimeters

Step-by-step explanation:

The volume of right circular cone is:

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

Where

r is the radius

h is the height

We are given height of 9.1 cm

h = 9.1

We aren't given radius explicitly, we are given circumference of 13.3, so we need to figure out radius from that. Lets do this:

$C=2\pi r\\13.3=2\pi r\\r=\frac{13.3}{2\pi}\\r=2.12$

So,

r = 2.12

Now, substituting in cone formula, we get the volume to be:

$V=\frac{1}{3}\pi r^2 h\\V=\frac{1}{3}\pi (2.12)^2 (9.1)\\V=42.83$

Rounded to nearest 10th is 1 decimal place, so

Volume = 42.8 cubic centimeters
