Rudik [331]3 years ago
4 0

Answer:

If the diameter is 18 then the radius r=9 so the area is:

πr2=81π≅254.469

Step-by-step explanation:

Explanation:

The area of a circle is given by the formula πr2 where r is the radius.

For each statement below, determine whether the statement is a decision variable or not.
Zarrin [17]

Answer and explanation:

Decision variables are variables that are independent(indeoendent variables) and can be controlled by the decision maker. Decision variables influence outcome or result of a solution, usually denoted x in linear programming.

Decision variables above include:

Number of Aqua-Spa Produced.

* Number of Hydro-Lux Produced.

* Number of Pumps Purchased.

* Amount of Available Labor Hours.

* Amount of Available Tubing Available

what could be a side length of a right triangle A.) 30 in, 45 in, 50 in B.) 30 in, 40 in,50 in C.) 30 in, 40 in, 60 in D.) 25 in
lions [1.4K]

The pythagorean theorem holds for every right triangle: given the legs a, b and the hypothenuse c, the triangle is right if and only if

a^2+b^2=c^2

So, you have to check:

30^2+45^2=2925\neq 2500 = 50^2

So the first triangle can't be a right triangle.

30^2+40^2=2500= 50^2

So the second triangle is a right triangle.

The third triangle can't be right, because it has the same legs but a different hypothenuse

Finally, we have

25^2+40^2=2225= 50^2

So the last triangle can't be a right triangle.

A cylindrical cookie jar has a volume of 904.23 cubic inches. It is 8 inches tall. What is the radius of the cookie jar? Round y
Mkey [24]

Answer:

Answer:

r = 6 in

Step-by-step explanation:

The volume of a cylinder of radius r and height or length h is

V = πr²h.

Here, we need to solve for the radius; we get:

     V

------------- = r²

     πh

                                       904.23 in³

This works out to    r² = ----------------- = 35.97 in²

                                            π(8 in)

Finally, take the square root of this result to find the radius, r:

r = √35.97 in² = 6 inches
