One circle is 1962.5ft. It’s 32 circles. So how many ft is that ?

I’m not sure of what to do ,can u please help me ?

Please I’ve been stuck on this for hours.

Out of 240,000 feet² of the field 62,800 feet² was being watered.

Step-by-step explanation:

We have a figure with 32 circles and diameter of each circle is 50 feet. We have to find how much area is being watered. Assuming that each circle represents the Area of the field which is being watered.

We can find the area of one circle and multiply that by 32 to find the area of all 32 circles. This will give us the area of the field that is being watered.

Since, radius is half of the diameter, the radius of each circle will be r = 25 feet.

Area of a circle is calculated as:

Area = πr²

Substituting the value of r = 25 and π = 3.14, we get:

Area of one circle = 3.14 x (25)² = 1962.5 feet²

Since area of 1 circle is 1962.5 feet² , area of 32 circles will be = 32 x 1962.5 = 62,800 feet²

The field is rectangular in shape with length = 600 feet and width = 400 feet.

Area of a rectangle is the product of its length and width. So area of the entire field will be:

Area of field = 600 x 400 = 240,000 feet²

This means, out of 240,000 feet² of the field 62,800 feet² was being watered.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
