Answer:

37.68ft³

Step-by-step explanation:

So the formula for the volume of a cylinder is base x height our height is 3 but we have to find the area of the base:

the formula is: radius² x 3.14 (pi)

so we find the radius by dividing the diameter by 2: 8 ÷ 2 = 4

4 x 3.14 = 12.56

So the area of the base is 12.56ft²

now we plug that into our equation:

12.56 x 3 = 37.68

So the volume of the cylinder is 37.68ft³

hope this helps:)

What is the value of es026-1.jpg?

Kay [80]

Answer:

Value of $[(\frac{2}{3}) ^0]^{-3}$ is, 1

Step-by-step explanation:

To find the value of $[(\frac{2}{3})^0]^{-3}$

Using exponents power rule:

$(a^m)^n = a^{mn}$

then;

$(\frac{2}{3})^{0 \cdot (-3)}$

Simplify:

$(\frac{2}{3})^{0}$

By Zero exponent rule: Anything raised to the power 0 is 1. i.e,

$a^0 = 1$

then;

$(\frac{2}{3})^{0}$ = 1

Therefore, the value of $[(\frac{2}{3}) ^0]^{-3}$ is, 1

If a variable has a distribution that is bell-shaped with mean 28 and standard deviation 5, then according to the Empirical R

mars1129 [50]

Answer:

99.7% data lies between 13 to 43

Step-by-step explanation:

Mean: $\mu = 28$

Standard deviation : $\sigma = 5$

68% of data lies between $\mu - \sigma$ to $\mu +\sigma$

95% of the data lies between $\mu - 2\sigma$ to $\mu +2\sigma$

99.7% data lies between $\mu - 3\sigma$ to $\mu +3\sigma$

We are supposed to find 99.7 of the data will lie between which values

99.7% data lies between $28 - 3(5)$ to $28 +3(5)$

99.7% data lies between 13 to 43

Hence 99.7% data lies between 13 to 43
