3,631.68 square units.
The diameter will be: 68/pi
Surface area of the ball = 4*pi*342 = 4624*pi square mm
The area of a circle is calculated by multiplying the square of its radius by pi and can thus be represented with the equation: A = πr^2 where A= area and r=radius. The radius of a circle is equal to half its diameter. Consequently the first step to answering this question would be calculating the radius of the circle. r= d/2 = 68/2 =34 miles This means that the formula to calculate the area for a circle with a diameter of 68 miles would be: A = π(34^2) Working this through would give us: A = π(34^2) = 1156 π = 3631.68 square miles (2 d.p.)
The area of a circle with a diameter of 9.4 m is: 69.4 m2

To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
The area of a circle with a diameter of 9.4 m is: 69.4 m2
A diameter is a line, and has no area.A circle whose diameter is 8.5 has an area of 56.745. (rounded)
The diameter of a circle with an area of 37.68 is 6.92
Divide the area by pi (= 3.14159 approx) to get diameter.
The diameter = sqrt (area*4/Pi) = 15.6353
Area = (pi/4) x (Diameter)2 Diameter = 2 x sqrt(Area/pi)
The area is four times as large if the diameter doubles.The area of a circle is A = (pi)r2 or (pi)(diameter/2)2Since d is squared, it increases the area by the square of 2 if the diameter is doubled.Try calculating the area for a diameter of 2m, 4m and 8m to prove this.
