What is the perimeter of a square that has an area of 36 feet?
A square cannot have an area of 36 feet since that is a measure of distance, not area. If, the square had an area of n SQUARE feet, then each side would be of length sqrt(n) feet. In that case, the perimeter would have been 4*(length of side) = 4*sqrt(n) feet.
Area of a rectangle 7cm by 11cm?
77cm. That should've been quite obvious.... all you do is multiply 7 by 11 and BAM, you have 77!
What is the area of the semicircle (use 3.14 for and rho)?
That would depend on the radius which has not been given but the area of the semi circle will be (pi*radius squared)/2
What is the exact area of a circle having a radius 6 in?
The formula for the area of a circle is pi times the radius squared, so if the radius is 6 inches, that is pi times 36 square inches. Pi is approximately 3.1415, which gives us an area of 113.094 square inches. If that is not exact enough, pi has been worked out to thousands of decimal places, and can be easily looked up on google.
What is the area a circle with a radius of 15.5?
152.98 (rounded to 2 d.p) I haven't included units as I haven't been given any but they would be the same units as the units given for the radius.
