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

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
How many square inches in a 4.25 inch circle?
A circle that is 4.25 inches implies that its circumference is 4.25 inches; that is, it is 4.25 inches around. The formula for the circumference of a circle is given as c = 2πr, where c is the circumference, pi is a constant (approximately 3.14), and r is the radius of the circle. Since the c-value is known we can use algebra to manipulate the formula in order to solve for r (the only missing piece of information). Doing so yields r = c/2π. Substituting the circumference of 4.25 inches into the formula reveals that the radius must be .68 inches (rounded to two decimal places). Now that the radius of the circle is known, the surface area can be calculated with the formula A = πr2. Substituting the determined value of the radius in for r produces a surface area of 1.45 inches2. The unit of square inches comes from the fact that we are not only multiplying the numerical value of the radius, but also its units. In this case, r2 = (0.68 inches)(0.68 inches) = 1.45 inches2.
Chords ab and CD of circle o intersect inside the circle find the measure of the acute angle formed if arc ac is 42 and arc db is 94?
If two chords intersect inside a circle, the acute angle they form is one half of the sum of the arcs intercepted by its sides and by the vertical angle SO... The acute angle will be one half the sum of the two arcs. So it is 1/2(42+94)=68 degrees.
What angle is 68?
An angle of 68 degrees is an acute angle
What is 68 divided by 8?
0.1176
How would you find the radius of a circle with a circle with a circumference of 68cm?
First, divide the circumference by Pi (about 3.1416): 68 / 3.1416 = 21.65 cm. This is the diameter. Now, divide the diameter by two to get the radius: 21.65 / 2 = 10.825 cm.The radius is: 10.825 cmNote: The result will vary slightly depending on the value you use for Pi
What is circumference of a circle with a radius in the length of 34 mm?

What is the radius of a circle with a circumstance of 68?
34 / pi
What is the radius of the sector when the angle is 21 and the arc length is 25?
Circumference of circle: 360/21 times 25 = 3000/7 Radius of sector: (3000/7) divided by (2*pi) = 68 units to the nearest integer
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

What is the volume of a soccer ball?
Because the circumference can vary from 68 to 70 centimeters, the volume is approximately 5310 to 5792 cubic centimeters(324 to 353.5 cubic inches).Circumference 68 cm = Radius 34/pi = Area 5309.77 cm3Circumference 70 cm = Radius 35/pi = Area 5792.19 cm3
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.)
What is the diameter if the circumference is 68?
The diameter will be: 68/pi
If a circle of radius 18.1 mm rotates through an angle of 68 deg what is the length of the arc created?
(2 pi) x (18.1) x (68/360) = 21.5 mm (rounded)
How do you find the number of circumferance inches in a 62x62x68x68 square?
There is no circumference of a square. The outside of a square would be the perimeter. That answer would be 62+62+68+68=260 Hope this helps.
