A square pyramid with a height of 7 inches has a volume of 47.25 cubic inches. Find the side length of the square base.

Romashka [77]

Answer:

4.5 inches

Step-by-step explanation:

volume= 1/3 (base area) × height

47.25= 1/3 ( base area) × 7

20.25 = base area

now since the base is a square we can evaluate base area = length²

20.25= length²

length = 4.5 inches

The length of a square is 256m and the breadth is 238m what is the perimeter

nikitadnepr [17]

The perimeter is 988 meters

Further explanation:

The given square has different length and breadth which means that the given square is a rectangle.

The formula for perimeter of a rectangle is:

$P=2L+2W$

Given

Length=L=256m

Breadth=W=238m

Putting the values in the formula:

$P=2(256)+2(238)\\=512+476\\=988\ meters$

The perimeter is 988 meters.

The surface area of a globe in Mr. Patton's classroom is about 152.39 square inches. Find its

Snezhnost [94]

Answer:

176.89in^3

Step-by-step explanation:

when finding the volume using the surface area, the best method that comes in my mind is finding the ratio between the surface area and volume which would be r/3 for a sphere. So if given that the surface area of the sphere is 152.39 square r/3=around 1.161, and when multiplied by 152.39 is around 176.89. another similar method is deriving the radius when given its surface area which is simply taking the square root of the surface area/4pi which turns out to be 3.482357088 or 3.48 which can then be plugged into the volume formula as the radius which is (3.48^3*4pi)/3 which turns out to be the same answer!

What is 17 37/50 turned into a decimal

FromTheMoon [43]

Because 17 37/50 is a mixed fraction, we must convert it into an improper fraction:

$17 \frac{37}{50}$
$17 * 50 = 850$
$850 + 37 = 887$
$\frac{887}{50}$

To make dividing the fraction easier, we can multiply the numerator and denominator by 2:

$\frac{887}{50} * \frac{2}{2} = \frac{1774}{100}$

Now it's easier to divide the numerator by the denominator:

$1774 \div 100 = 17.74$

17 37/50 converted into a decimal is 17.74.
