What is the formula for finding the perimeter of a quads?

VLD [36.1K]

The formula for finding the perimeter of a quadrilateral is Length + Length + Width + Width.

<h3>What is Perimeter?</h3>

A perimeter is the path that surrounds a certain shape. To calculate the path that surrounds a quadrilateral, we need to get the sum of its four sides, both lengths and widths, lengths being the longest sides and the widths being the shortest.
The formula used for calculating perimeter is Perimeter = Length + Length + Width + Width.
For instance, to calculate the perimeter of a parallelogram with a side of 5 cm and one of 3 cm, we insert the numbers in their corresponding spot in the formula as such: Perimeter=5+5+3+3=16 cm or since parallelograms have 2 sets of 2 equal sides, we can use this formula Perimeter=(5×2)+(3×2)=10+6=16 cm.
For a square on the other hand, we only need to know the length of one side because it has 4 equal sides.

Therefore, the formula for finding the perimeter of a quadrilateral is Length + Length + Width + Width.

A hemispherical dome of a building needs to be painted. If the circumference of the base of the

soldier1979 [14.2K]

Answer:

The cost of painting the hemispherical dome is 110880 unit

Step-by-step explanation:

Given as for a hemispherical dome :

The circumference of base = 17.6 m

The cost of painting it = 5 unit per 100 cm²

∵ circumference of base = circumference of circle = 2× $\pi$ ×radius

So ,17.6 m = 2× $\pi$ ×radius

Or, Radius = $\frac{17.6\times 7}{2\times 22}$

Or, Radius = $\frac{123.2}{44}$ = 2.8 m

Or, R = 280 cm

So, Total surface area of hemispherical dome = 3× $\pi$ ×radius²

or, Total surface area of hemispherical dome = 3× $\pi$ ×280²

Or, Total surface area of hemispherical dome = $\frac{3\times 22\times 280\times 280}{7}$

Or, Total surface area of hemispherical dome = $\frac{5174400}{7}$

∴ Total surface area of hemispherical dome = 739200 cm²

Now, The cost of painting 100 cm² is 15 unit

So, The cost of painting 739200 cm² = $\frac{15\times 739200}{100}$

Or, The cost of painting 739200 cm² = 110880 unit

Hence The cost of painting the hemispherical dome is 110880 unit Answer

How much interest would be earned on $3,700 in one year if it is invested at 4%?

malfutka [58]

I'd say $148 because you convert the percent into a decimal so
4%= 0.04

Then you multiply $3,700•0.04 = $148

So I'd say the interest earned on $3,700 in one year would be $148
