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
= 64/2
=32 miles
This means that the formula to calculate the area for a circle with a diameter of 64 miles would be:
A = π(32^2)
Working this through would give us:
A = π(32^2)
= 1024 π
= 3216.99 square miles (2 d.p.)
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.)
Diameter of the circle: 31.4/pi = 10 miles rounded up
Circumference of the circle: 38*pi in miles

pi x d2/4=3.1416 x 82x82/4 = 5281 sq. miles approx.

The diameter of a circle who's circumference is 28.26 miles is: nine (9) miles
The circumference of a circle-shaped lake with a diameter of 2 miles is: 6.283 miles (diameter x Pi = circumference).
Circumference of the circle: 38*pi in miles
That depends whether the "10-mile circle" refers to the circle's radius, its diameter, or its circumference. Assuming it is the diameter, divide it by 2 (to get the radius), then use the formula: area = pi x radius2.
Its diameter will be: 2*100 = 200 miles
24888.93 miles
A ≈ 126,000 square miles.
