Answer:

Length of arc = 0.628 r

Step-by-step explanation:

Given:

∠ AOB = 36°

Radius = (r)

Find:

Length of arc AB = ?

Computation:

$Length\ of \ arc = \frac{\theta}{360}2\pi r\\\\Length\ of \ arc = \frac{36}{360}(2)(\frac{22}{7} ) (r)\\\\Length\ of \ arc =0.628r$

Length of arc = 0.628 r

What is the volume of a cone with a radius of 2 and a height of 19?

kykrilka [37]

Remember that the cone volume formula is $V=\pi r^2\frac{h}{3}$ , with r = radius and h = height. Using our information, we can form our equation as such: $V=\pi 2^2\frac{19}{3}$ (I'll be keeping the answer in pi form.)

Firstly, solve the exponents: $V=\pi 4\frac{19}{3}$

Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3

what's the difference between (-4)^-3 and -4^-3. basically what's the difference when there's parenthesis for the base number?

NNADVOKAT [17]

(-4)^-3 = $\frac{1}{-64} or -0.015625$
-4^-3 = $\frac{1}{-64} or -0.015625$

Basically in this situation there is no difference whether parenthesis are used or not.
