It depends on the shape or figure your trying to find it for.
Area- the area of a flat or plane figure is the number of unit squares that can be contained in it.
Volume- Is the measure of the amount of space in a closed figure.

The formula for the area of any regular polygon is 1/2 the product of the apothem and the perimeter. The area of a circle is $\pi r^{2}$ with the r standing for "radius".

The formula for the volume of any prism or cylinder is the area of the base times the height of the prism or cylinder. The volume for a sphere is 4/3 the product of $\pi r^{2}$ with the r standing for radius.

There are countless other formulas for volume and area, so if the one you are looking for is not here please comment the formula you're looking for and I'll happily supply you with it!

The figure consists of a quarter circle and a parallelogram. What is the area of the composite figure? Use 3.14 for pi. Round to

Andru [333]

The area of a full circle is given by
A = π*r^2
so the area of a 1/4 circle will be 1/4 of that:
A = (π/4)*r^2

The area of a parallelogram is the product of base length and height:
A = bh

Your composite figure will have an area that is the sum of the areas of the parts.
A = (quarter circle area) + (parallelogram area)
A ≈ (3.14/4)*(14 in)^2 +(14 in)*(5 in)
A ≈ 223.86 in^2 ≈ 224 in^2

The most appropriate selection is the last one,
224 in^2

Answer:

Minimum = 10

Q1 (quartile 1) = 14.5

Medium = 16

Q3 (quartile 3) = 17

Maximum = 18

Step-by-step explanation:

You just arrange the numbers in from smallest to greatest (even if some of them repeat). Then, look for the maximum and minimum. Get the median by having the same numbers left from both sides until reaching the median. The same holds for the quartiles (if you have for example two numbers for the quartile, as in this case 14 and 15, add the up and divide them by 2, in this case 14.5.

Tell me if I'm correct please
