A circle with circumference 30 in has area = 302 ÷ (4π) ≈ 71.6 in2 < 100 in2 so a square of area 100 in2 cannot fit inside it.
Yes because the diameter of the circle is less than the sides of the square.
The answer depends on their relative size: is the circle inside the square, the square inside the circle or something else?
It is: 128/4 = 32 which is a side of the square and so 32*pi is the circumference of the circle
The is not stated that the circle inside the square was the greatest possible circle, so all one can say is 8pi at most.
It is its square area which is found by pi*radius squared

To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
the circumfrence of a circle is pi times it's radius squared.
Multiply the diameter by 3.1415 NO - ignore that! Diameter x pi (3.1416) is the circumference, the distance around a circle. Square footage is area, so the correct formula is Area = 3.1416 times radius squared. The radius would be measured in feet.
The area of a circle is (pi x radius squared) A = πr2 The circumference is (pi x diameter) C = π (2r) So if you have the circumference, the area is the circumference squared, divided by 4pi (about 12.566). A = C2/4π Example: A circle with a diameter of 6 inches has a radius of 3 inches Area A = pi (32) or about 28.27 square inches Circumference C = pi (6) or about 18.85 inches Using C2/4pi, the area is 18.85 x 18.85 / 12.566 = about 28.27 square inches
