area of full circle = 400 sq. ft.
if area = pi * radius2
then radius = square root ( area / pi )
= 11.284 radius (approx).
= 22.568 diameter (approx).

What is the area of the semi circle 30 feet?
Is the 30ft the radius or the diameter. The area of a circle = Pi x (radius squared), so, if the diameter is 30ft, making the radius 15ft, the area would be Pi x(15 squared) square feet, and the area of its semicircle would be half of that, so the area required = Pi x (15 squared) divided by 2 = 353.429 sq ft On the other hand, if the diameter is 15ft, making the radius 7.5ft then the area required = Pi x (7.5 squared) sq ft for the full circle and half as much for the semicircle = 88.3573 sq ft As an extra; you will find that the area of the smaller semicircle is exactly one quarter of that of the larger semicircle, and I wonder if you can reason out why that is so.
What would the perimeter of a 20ft semicircle be?
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft
What are the dimensions of a 300 sq ft rectangular room?
It could be 1 x 300 ft. It could be 2 x 150 ft. It could be 3 x 100 ft. It could be 4 x 75 ft. It could be 5 x 60 ft. It could be 6 x 50 ft. It could be 10 x 30 ft. It could be 12 x 25 ft. It could be 15 x 20 ft. . . . etc. There are an infinite number of things it could be. The area doesn't tell you the dimensions.
How many 12x12 squares do you need to cover 200 square feet?
Assuming that the 12x12 is inches.12 in. x 12 in. = 1 ft x 1 ft = 1 square (sq) footGiven that you have 200 square feet to cover:(200 sq ft) / (1 sq ft) = 200 unitsThat means it takes 200 12x12 in. squares to cover a 200 sq ft. space.If you meant 12x12 to be in feet:12 ft x 12 ft = 144 sq ft.200 / 144 ~= 1.39 units (It would take 1.39 squares to cover it)
Which is bigger 66 yd or 200 ft?
It is: 200 feet
The radius of the semicircle is 5 feet and the dimensions of the rectangle are 10 ft by 16 ft The semicircle is attached to the width of it What is the perimeter?
Perimeter = (2*pi*5*1/2)+10+16+16 = 57.70796327 or 58 feet
Is 200 sq ft X 200 sq ft an acre?
No. 200 sq ft x 200 sq ft is a measure of hyper-area in 4-dimensional space. Space, as we perceive it, has only 3 dimensions and, within it, an acre is a mere 2-dimensional measure.
What are the dimensions of a rectangle with a perimeter of 401 feet and an area of 100 feet?
The rectangle cannot have an area of 100 feet, since that is a measure of distance and not area. Assume, therefore, that the area is 100 SQUARE feet. Suppose the rectagle has length L and width W then 2(L + W) = 401 and L*W = 100 So L = 100/W Then 2(100/W + W) = 401 Multiply by W: 2(100 + W2) = 401W or 2W2 - 401W + 200 = 0 or (2W - 1)(W-200) = 0 So W = 0.5 ft or W = 200 ft which imply that L = 200 ft or 0.5 ft respectively. So, the dimensions are 200 ft by 0.5 ft (or 6 inches).

If 2 rectangles have the same area must they have the same perimeter?
Not at all.Rectangle A:-- Length = 20-ft, Width = 10-ft.-- Area = 200 square ft-- Perimeter = 60-ftRectangle B:-- Length = 16-ft, Width = 12.5-ft-- Area = 200 square ft-- Perimeter = 57-ftRectangle C:-- Length = 40-ft, Width = 5-ft-- Area = 200 square ft-- Perimeter = 90-ftRectangle D:-- Length = 50-ft, Width = 4-ft-- Area = 200 square ft-- Perimeter = 108-ftRectangle E:-- Length = 100-ft, Width = 2-ft-- Area = 200 square ft-- Perimeter = 204-ftRectangle F:-- Length = 800-ft, Width = 3 inches-- Area = 200 square ft-- Perimeter = 1600-ft 6-in
What percent of 200 ft is 7 yd?
first get the two dimensions in the same units: 7 yd * (3 ft/yd) = 21 ft.Now divide: (21 ft) / (200 ft) = 0.105 ---> 10.5 %
