Find the volume of a cone whose height is 7.5cm and the base diameter is 7cm pi=22/7

xz_007 [3.2K]

Answer:

92.64 cm^3 (it should be smaller if using actual pi, 22/7 is larger than pi)

Step-by-step explanation:

The equation for the volume of a cone is 1/3(pi*h*r^2) So, first we need to find the radius, which is diameter over 2, so the radius is 3.5 cm. Now we know all of the variables so we can plug in to solve.

Brainliest if correct

Hello! Hope you are having a nice day! :)

The 1st step is to get rid of the 2:
$-6=\displaystyle\frac{w}{2}$
$-6-2=\displaystyle\frac{w}{2}$
$-8=\displaystyle\frac{w}{2}$
Now, multiply both sides by 2 to get rid of the fraction:
$w=-16$

Hope it helps!
