The formula for a circumference of a circle is: C=2π<span>r
and we are given the answer as
C=16</span><span>π

Therefore we know that 16 is from the combination of multiplying 2 and r
So to find r we do the opposite of what is done. The opposite of multiplying is dividing, therefore:
16/2=8
therefore r = 8

The formula for the area of a circle is: </span>A=πr^<span>2
Since we know r = 8 we just sub it into the equation

A=</span><span>π*8^2
A=64</span><span>π or (assuming you want π to two decimal places: 3.14 then) 200.96</span>

A sandbox has an area of 10 2/3 square feet, and the length is 1/4 feet. What is the width of the sandbox?

AlekseyPX

Answer:

The width of the sandbox is $42\frac{2}{3} \ ft$ .

Step-by-step explanation:

Given,

Area of the sandbox = $10\frac{2}{3}=\frac{32}{3}\ ft^2$

Length = $\frac{1}{4}\ ft$

Solution,

Let the width of the sandbox be 'w'.

Since the sandbox is in shape of rectangle.

So we use the formula of area of rectangle.

$Area = Length\times Width$

On substituting the given values, we get;

$\frac{1}{4}\times w=\frac{32}{3}\\$

By cross multiplication method, we get;

$w=\frac{32\times4}{3\times 1} =\frac{128}{3} =42\frac{2}{3} \ ft$

Hence The width of the sandbox is $42\frac{2}{3} \ ft$ .
