A circular sign is precisely designed to have an area of 50.24 square inches. What is the sign's circumference?

choli [55]

Step-by-step explanation:

First of all we need to know the formula for the circumference which is: $c=2\pi r$

We don't have the radius. What we only have is the area; therefore, we must use the area formula and extract the radius from it.

The formula for the area is: $A=\pi r^2$ Solve for r;

$r^2=\frac{A}{\pi}\\ r=\sqrt[]{\frac{A}{\pi} }$

$r=\sqrt[]{\frac{50.24inch^2}{3.14} }$

$r=\sqrt[]{16inch^2}\\ r=4inch$

Now that we've found the radius, we simply plug it into the circumference formula.

$C=2\pi r\\C=2(3.14)(4)\\C=25.12inch$

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area f

myrzilka [38]

Answer:

The sprinkler can spread water 18 feet away.

Step-by-step explanation:

We are given the following in the question:

Area formed by watering pattern = 1,017.36 square feet

We have to find the how far the sprinkler spread the water.

The sprinkler covers a circular area. We need to find the radius of this circular area to find the how far the sprinkler spread the water.

Area of circle =

$A = \pi r^2$

where r is the radius of the circle.

Putting values, we get,

$1017.36 = 3.14 r^2\\\\r^2 = \dfrac{1017.36}{3.14}\\\\r^2 = 324\\r = \sqrt{324} = 18\text{ feet}$

Thus, the sprinkler can spread water 18 feet away.
