Answer:
28.26 ft^2
Step-by-step explanation:
Area of a circle is calculated using the following formula :
πr^2 (r: radius, and π is given as3.14)
the diameter is given as 6 and radius is equal to half of it so :
(3.14)*3^2 = 28.26 ft^2
If I'm correct and the ^ stands for multiplication then the answer should be 5.
The picture is my work just ignore the fraction.
12*14*3= 504 square feet
504/42= 12
C. 12 rolls
If
then we also have
Pairing up the terms, we can find that
consists of terms, so there are copies of in the sum . Then we find an immediate closed form for the sum:
Answer:
or
Step-by-step explanation:
Given
Points:
A(-3,2) and B(-2,3)
Required
Determine the radius of the circle
First, we have to determine the center of the circle;
Since the circle has its center on the x axis; the coordinates of the center is;
Next is to determine the value of x through the formula of radius;
Considering the given points
Substitute values for in the above formula
We have:
Evaluate the brackets
Eva;uate all squares
Take square of both sides
Evaluate the brackets
Collect Like Terms
Divide both sides by 2
This implies the the center of the circle is
Substitute 0 for x
Substitute 0 for x and y in any of the radius formula
Considering that we used x1 and y1;
In this case we have that;
Substitute -3 for x1 and 2 for y1
