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? :)
Wha is the radius of a circle?
The radius of a circle is half the circle's diameter
What is the radius of a circle where d is the diameter of the circle?
the radius of a circle is r
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.
What is the formula for the circumstance of a circle where r represents the radius of a circle and c represents the circumstance of a circle.?
A circle does not have a circumstance. Assuming that you mean circumfernece, the answer is c = 2*pi*r
What is Circumstances of a circle?
The circumstance of a circle is 2 x pi x radius. I.e.: if the circle has a radius of 6, the circumstances 12×π which is 37.6991118432
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
Which equation can be used to find circumstance C of a circle with radius that measures 16 ft?
I don't know if this is what you are after, butthe circumference (not circumstance) C is 2*pi*r where r is the radius (not radious, as you spell it).
What is the circumstance of a circle with a radius of 5 units?
Circumference of circle: 2*pi*5 = 31.416 units rounded to 3 decimal places
What is the circumstance of a circle with a radius measuring 6 cm?
Circumference of the circle: 2*pi*6 = 37.699 cm rounded to 3 decimal places
What is the radius of a circle that has area of 68 square feet?
Area of circle = pi*r^2 so......... 68 sqr ft = pi * r^2 divide both sides by pi 21.645 = r^2 take square root of each side 4.7 feet = the radius of this circle
A circle has a diameter of 7cm what is it's area and circumstance?
The area of a circle is pi*r2 and its circumference is 2*pi*r where r is the radius = half the diameter. So r = 3.5 cm. Then area = 38.48 square cm and circumference = 21.99 cm As to the circumstance of the circle, that is rather a personal question!

What is circumference of a circle with a radius in the length of 34 mm?
68 pi mm ie 213.6 mm to the nearest tenth
How do you find the radius of a circle if the circumference is 68?
C (Circumference) = 3.14 (pi)*D (diameter) r (radius) = 0.5D and D = 2r So circumference can also be C=3.14*2r Then, solve 68 = 3.14*2r to get r = 10.83
