Which is the formula to calculate area for a circle with diameter of 68 miles?
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.)
If the circumstance of a 1 circle is equal to the diameter of the 2 circle then what is the area of the 2 circle?
let the circumference of the first circle be X. The formula for the area of a circle is pi multiple by radius squared. pi can be y so it is yr2. The radius for the second circle is half the diameter so half X. therefore the are is y(0.5X)2. BTW: is this your homework? :)
What is the radius of a circle where d is the diameter of the circle?
the radius of a circle is r
Wha is the radius of a circle?
The radius of a circle is half the circle's diameter
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
