Volume of a Cone Formula: $\displaystyle V = \frac{1}{3} \pi r^2h$

r is radius
h is height

Step-by-step explanation:

Step 1: Define

Radius r = 4

Height h = 21

Step 2: Find Volume

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (4)^2(21)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (16)(21)$
Multiply: $\displaystyle V = \frac{16 \pi}{3}(21)$
Multiply: $\displaystyle V = 16 \pi \cdot 7$
Multiply: $\displaystyle V = 112 \pi$

Which of the following is equivalent to 5√13^3?

sergeinik [125]

LOL...it took me a few seconds to realize what you were attempting to express...which is the fifth root of 13 cubed...

(13^3)^(1/5) rule: (a^b)^c=a^(b*c)

13^(3*1/5)

13^(3/5)
