Yes because the diameter of the circle is less than the sides of the square.
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.
The is not stated that the circle inside the square was the greatest possible circle, so all one can say is 8pi at most.
If Mark makes a circle, that circle would have a circumference of 12 inches. The formula for circumference is pi times diameter, so the circumference divided by pi will give you the diameter of 3.82 inches. Divide this by 2 to get the radius of 1.91 inches. Area of a circle is pi times the radius squared. 1.91 squared is 3.6481. Multiply this by pi to get 11.46 square inches of area inside the circle. A circle is always the most efficient use of space possible given a fixed perimeter. If Mark makes a square with equal sides where all sides are 3 inches, the area would be 9 square inches. 3 X 3 = 9
Divide 39 by pi to find the diameter of circle 1 and then subtract four inches from your answer to give the diameter of circle 2.Circle 1 = 39/pi = 12.41408556 inchesCircle 2 = 12.41408556 - 4 = 8.41408556 inches
Yes because each side of the square is 10 inches and 30/pi gives the circle's diameter as 9.549296586 or about 9.5 inches
yes
the circumference is pi times the diameter. the area is pi times radius-squared. And, of course, the Circumference is the distance around the circle, or the outside. While on the other hand, the area of a circle is the amount of space on the inside of a circle:) hope this helps !

The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.

A circle with a diameter of 8 would have the circumference of 2.54. This is the measurement inside the circle.
u cant have circumference inside a circle inside of a circle is called area out side the circle its called circumference. If you are calculating the circumference the formula is C(circumference)=pi(3.142)*d(diameter) so its C=pi*d note: if u want the accurate result press pi on a calculator which is like a table but the surface of the table is sticking out. now for the area A(area)=pi(3.142)*r squared(radius) so its A=pi*r squared. so heres an example work out the circumference if the diameter is 5cm so you do 5cm which is the diameter and multiply it my pi. So the answer is for two decimal place is 15.71cm here's another example using the radius the radius is half the diameter so in this case the radius is 2cm multiply it my two which gives 4 and then multiply my pi. Now example for area the radius is 3 but then i have to square it so i do 3(squared) which is 9cm(squared) then * pi which will give you 28.27cm(squared) area is inside a shape. hope this helped if you need help e-mail me at: nik.kita@hotmail.co.uk
The area of a circle is the amount of space inside the circle. The circumference of a circle is the distance around the outside of the circle. (So no, they are not the same thing.)
