The circumference of a circle with a 10in radius is: about 62.83 inches. (r x 2 x pi = circumference).

No. To biggest circle you could draw in a square with 100in would be one with a radius of 5in (10in diameter) since the squares dimensions will be 10in x 10in. So, working out the circumference with this radius: 2 x pi x 5 = 31.4 inches, which is greater than the 30 inches you want.

Area = 14in x 20in = 280in2 Area = 10in x 12in = 120in2

Multiply the two dimensions to get the area. In this case the calculation gives you 7,708 square inches, which divided by 144 gives you 53.53 square feet.

Area of a circle = pi*radius2

25 square inches.Method:The area of complete circle is Pi x radius2 which is 3.14159 x 5 x 5, = 78.53982 sq ins.The circumference of a circle is Pi x diameter, which is 3.14159 x 10, = 31.4149 ins.But the arc is only 10/31.4159ths of the length of the full circle (10 divided by 31.4159 is 0.3183).So the area of sector with an arc 10 inches in length is: area of full circle (78.53982) x 0.3183 = 25.The above figures are only to a few significant decimal places. If you do the computations on a computer or a calculator the answer will come to exactly 25

Circumference=(pi)Xdiameter, diameter=Circumference/(pi)=(10in)/(3.14)=3.183in Area=(pi)d2/4=(pi)[Circum/(pi)]2/4=Circum/(4pi)=0.7957~8 square inches.

The area would be 78.53 squared inches. Formula: PI (x) Radius squared = Area Radius is half of the diameter of the circle. So the radius is 5 Inches. (10 divided by 2 = 5) 3.14 x 5 squared = Area ---> 3.14 x 25 = 78.53981634 Hope that helped

70 square inches

Area = 14in x 20in = 280in2 Area = 10in x 12in = 120in2

A rectangle with sides of 6 inches and 10 inches would have an area of 60 square inches.

Area triangle = 1/2 base x height Area square = length x width = 10in x 10in = 100sq in. Area triangle = area square Therefore: 1/2 x 10in x height = 100sq in height = 100 sq in x 2 / 10 in = 20 in
