What mutiplication equals to 1400

Answers

140 x 10 equals 1400 and 70 x 20 equals 1400

The answer is 200 and 700 either of them would be the right answer.

For Example 2x7=14 but when you multiply 700x2=1400 or 200x7=1400.

If you don't understand ty dividing 1400 to 2 it will equal 700.

a stained glass window is shaped like a semicircle. the bottom edge of the window is 36inches long. what is the area of the stained glass window? round your answer to the nearest hundreth

Answers

The formula for the area of a semicircle is equivalent to the area if it were a circle divided by 2. Since the bottom edge of the window is 36 inches long, this means that its diameter is also 36 inches long. This gives an area of 508.94 square inches.

The solution is:

A = Acircle/2 = pi*r^2/2 = pi*(18)^2/2 = 508.94 in^2
