A cone shaped paper cup is 2.5 inches high and has a diameter of 3 inches. Ehat is volume to the nearest hundredth

1 answer:

8 0

If the diameter is 3, the radius is half that, or 1.5.

$\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}~~
\begin{cases}
h=2.5\\
r=1.5
\end{cases}\implies V=\cfrac{\pi (1.5)^2(2.5)}{3}\implies V=\cfrac{5.625\pi }{3}$

Suppose a farm has pens for raising insects. A pen is shaped as a rectangle that measures x meters wide and 2x meters long and h

Ludmilka [50]

Answer:

1.2 meters.

Step-by-step explanation:

Length of pen = 2x meters

width of pen = x meters

shape of pen is rectangular

we know that area of rectangle is given by length * width

Thus, area of the pen is x*2x = $2x^2$

It is also given that area of pen is 2.8 square meters.

Equating numerical value of area with area in terms of x, we have

$2x^2 = 2.88\\=> x^2 = 2.88/2\\=> x^2 = 1.44\\=> x = 1.2$

Thus value of x is 1.2 meters.
