How do you find the length and width of a rectangle when you are given the area
larisa [96]

Area = length x width. So, you can't find the actual length and width from the area because there are infinite possibilities.

But you can figure out a set of likely solutions. For example:

If A = 35   l = 1, 5, 7, 35    and    w = 1, 5, 7, 35.

We now know that the length and width must be one of these 3.

Even if the area is a prime number, there are still infinite fractional possibilities.

So, there really is no way to actually find the length and width from the area.

Answer:

384π cm³

Step-by-step explanation:

Formula for the volume of a cone is \displaystyle \large{\frac{1}{3}\pi r^2 h} where:—

  • r is radius
  • h is height

Our radius is given in an attachment which is 12 cm and height is 8 cm. Substitute these values in the formula:—

\displaystyle \large{V = \frac{1}{3}\pi (12)^2 \cdot 8}\\\displaystyle \large{V = \frac{1}{3}\pi \cdot 144 \cdot 8}\\\displaystyle \large{V = 48 \pi \cdot 8}\\\displaystyle \large{V = 384 \pi}

__________________________________________________________

<u>Summary</u>

  <u>Volume (Cone)</u>

\displaystyle \large{V = \frac{1}{3}\pi r^2 h} where:—

h is height or perpendicular.

r is radius.

  <u>Value of Pi (Commonly Used)</u>

\displaystyle \large{\pi \approx 3.14}

Step-by-step explanation:

1.C. circumference

2.D. 25.12 decimeters

Solution

C=2πr=2·π·4≈25.13274

3.B. 28.26 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·9≈28.27433m

4.B. 25.12 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·8≈25.13274m

5.B. 21.98 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·7≈21.99115m
