Answer:

189

Step-by-step explanation:

The pyramid has four triangular faces and a square base.

The area of a triangle is half its base times its height. The base of each triangle is 7, and the height of each triangle is 10. So the area of each triangle is A = ½ (7) (10) = 35.

The area of a square is the side length squared. The side of the square is 7. So the area of the square is A = (7)² = 49.

The total surface area is:

A = 4(35) + 49

A = 189

Find the radius and diameter of a circular puddle whose

o-na [289]

Answer:

$r = 35cm$

Step-by-step explanation:

Given

$C = 220cm$

$\pi = \frac{22}{7}$

Required

Determine the radius

Circumference (C) is calculated as:

$C = 2\pi r$

Where r represents radius

Substitute values for C and $\pi$

$220cm = 2 * \frac{22}{7} * r$

$220cm = \frac{44}{7} * r$

Multiply through by 7/44

$\frac{7}{44} * 220cm = \frac{7}{44} * \frac{44}{7} * r$

$r = \frac{7}{44} * 220cm =$

$r = \frac{7 * 220cm }{44} =$

$r = \frac{1540\ cm}{44}$

$r = 35cm$

<em>Hence, the radius is 35cm</em>

Calculate the standard deviation of the volume of water at a temperature of 25°C.

vaieri [72.5K]

Answer:

0.01

Step-by-step explanation:

Water is non viscous liquid and it has less density. The measure volume of water is 10.03 ml at 25 degree Celsius which is used to identify the standard deviation of the water.

Average volume of water 10.03ml.

Standard deviation is 0.0001 + 0.0001

Standard deviation is $\sqrt{0.0002}$ = 0.01.
