Answer:

Volume = 175.93km ^3

Surface Area = 753.97km ^2

Step-by-step explanation:

Cylinder surface area =A=2πrh+2πr2

Volume = V=πr2h

We plug in

Area = 2 x π x 8km x 7km =2π 56 = 351.85km ^2

= 351 858 377 m^2

+ 2πr2 = 2 x π x 64 = 402.12km^2

Surface Area = 2π 56 + 2π x 64

402.12 + 351.85 =753.97km ^2 = 753 97 8377 m^2

Volume = π x 8 x 8 x 7 = 448π = 1407.43km ^2

= 140.743m^3

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to *

torisob [31]

Answer:

Step-by-step explanation:

Coefficient of variation is a measure of dispersion, showing the variability of data in relation to the mean.

The Coefficient of variation compares the degree of variation between data points. The coefficient of variation is the ratio of mean to standard deviation. It is given by the formula:

Coefficient of variation = mean / standard deviation

Coefficient of variation = 50 / 5

Coefficient of variation = 10

When drawn in standard position, in which quadrant does the terminal side of the angle −240° lie?

valina [46]

Answer:

Option (2)

Step-by-step explanation:

All angles are positive when measured counterclockwise from the x-axis.

Terminal side of 240° degrees when measures counterclockwise will lie in the 3rd quadrant.

But the angle is -240°.

That means angle is being measured clockwise from the x-axis.

Therefore, terminal side of the of the angle will be in the 2nd quadrant.

Option (2) will be the correct option.

If x3 = 27, what is the value of x?

ipn [44]

Answer:

The value of x is 3

Step-by-step explanation:

Given:

$x^3 = 27$

To Find:

x = ?

Solution:

We Know that

$a = (a^3)^\frac{1}{3}$

$a = (a)^\frac{3}{3}$

We can write 27 as $3 \times 3 \times 3$ = $3^3$

Taking cube root on both sides

$(x^3)^{\frac{1}{3} }= (3^3)^{\frac{1}{3}}$

$x^{\frac{3}{3}} = 3^{\frac{3}{3}}$

$x^1 = 3^1$

x = 3
