Is it possible to draw a circle with a circumference of 30in inside a square with an area of 100 in2?

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.

What is the area of a sector of a circle that has a diameter of 10in if the length of the arc is 10in?

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


If the circumference of a circle is 10 inches what is the area in square inches of the circle?

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.


What is the area of a circle with a diameter of 10in.?

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

What is the area of 14 in and 20 in and 10 in and 12 in?

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


What is the area of 6in and 10in?

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


A square and a triangle have equal areas and a side of the square is 10 inches and the base of the triangle is 10 inches then what is the height of the triangle?

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
