The problem gives you the formula for the volume of a cone - you just need to find the values for the variables. In this case, we can see $h = 6$ and $r = 5$ . Thus, by using the formula with $\pi \approx 3.14$ , we can solve for the volume $V$ :

$V \approx \dfrac{1}{3} (3.14) (5^2) (6)$

$V \approx 157$

The volume is approximately 157 ft.

Pyramid A is a square pyramid with a base side length of 18 inches and a height of 9 inches. Pyramid B has a volume of 3,136 cub

Basile [38]

The volume of pyramid B (3,136 in.³) is 323% bigger than the volume of pyramid B (972 in.³).

<h3>What is the Volume of a Square Pyramid?</h3>

Volume of square pyramid = 1/3(a²)h

Given the following:

Volume of pyramid B = 3,136 in.³
Base side length of pyramid A (a) = 18 in.
Height of pyramid A (h) = 9 in.

Volume of square pyramid A = 1/3(a²)h = 1/3(18²)9 = 972 in.³

3,136/972 × 100 = 323%

Pyramid B volume is 323% bigger than the volume of pyramid A.

Find a cartesian equation for the curve and identify it. r = 10 tan(θ) sec(θ)

Vilka [71]

For a cartesian equation
$x=r\cos\theta \ and \ y=r\sin\theta \\ \\ \cos\theta=\frac{x}{r} \ and \ \sin\theta=\frac{y}{r} \\ \\ \tan\theta=\frac{\sin\theta}{\cos\theta}=\frac{y}{r}\cdot\frac{r}{x}=\frac{y}{x} \\ \\ \sec\theta=\frac{1}{\cos\theta}=\frac{r}{x}$

Given r = <span>10 tan(θ) sec(θ)
$r=10\tan\theta\sec\theta=10\cdot\frac{y}{x}\cdot\frac{r}{x} \\ \\ \Rightarrow10y=x^2 \\ \\ \Rightarrow y= \frac{1}{10} x^2$

Therefore,</span>the curve is a parabola opening upward with vertex (0, 0).

The rectangle shown has a perimeter of 156 cm and the given area. Its length is 6 more than five times its width.

Stells [14]

P=156 cm
l=6+5w
P=2(l+w)
156=2(6+5w+w)
156=2(6+6w)
156=12+12w
12+12w=156
12w=156-12
12w=144
w=12cm

l=6+5•12
l=6+60
l=66cm
