Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you estimate square footage?

Square footage is the length of your room times the width. For a circular room, measure the diameter (length across the circle), divide by 2 to get the radius (length across half the circle), multiply by pi and square it. The formula for the area of a circle is πr^2, and Pi (π)= 3.1416

The length of your garden is 11 feet by 6 feet at it maxium width you are attempting to make a half circle garden how would you figure out square footage?

Assuming your aim is the largest semicircle within the rectangular area, it would be a half circle of radius 5.5 ft. A circle's area is Pi times the radius squared, so the half circle would be 1/2 * 3.14 * 5.5 * 5.5 , which equal 47.5 square feet.


How do you calculate area of circle?

1. Multiply pi (3.14) by the radius of the circle (half of the diameter which is the length of the circle on the widest part).2. Square your result.This uses the formula:Area=πr2where π=3.14

Why is the area of a circle bigger than a square with the same perimeter?

It is not. If you draw yourself a square then inscribe a circle with a radius of half the length of a side of the square, the circle will fit inside the square but the corners of the square will be outside the circle. Thus by inspection the area of the square is larger than the area of the circle.


Is the area of a circle bigger than the area of a square?

It depends on the diameter of the circle and the width of the square, if they are the same then the answer is no. If you draw yourself a square then inscribe a circle with a radius of half the length of a side of the square, the circle will fit inside the square but the corners of the square will be outside the circle. Thus by inspection the area of the square is larger than the area of the circle.


If a circle is placed inside an 800ft squared area what is the radius of the circle?

Well, since the circle is inside the square, the edges of the square define the limits of the circle. Since we have a square, the length of each side is the square root of 800ft. The radius of the circle is half the length of the sides. Therefore, the answer is half of (the square root of 800), which makes for an ugly radius value of "14.142135623730950488016887242097" ft
