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.
The area of a circle when the circumference is 10 inches is: 7.96 square inches.

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

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