Find the area of the circle shown with radius r equals 5 m?
25 pi sqm
What is area of a cylinder with r equals 1 h equals 5?
The area of a cylinder is 2 x pi x the radius (r) x (radius + height) 2.pi.r.(r+h) = 2x3.143x1(1+5) = 6.286(6) = 37 square cm or what ever the units are ( you don't say what the units are)
What is the area of a cirle with a radius of 5 in?
The area of a circle of radius r is pi*r*r
How many square miles in a 5 mile radius?
To calculate the area of a circle with a radius of 5 miles, you would use the formula A = πr^2, where A is the area and r is the radius. In this case, the area would be A = π(5)^2 = 25π square miles. Since π is approximately 3.14, the area would be approximately 78.5 square miles within a 5-mile radius.
Diameter equals 6cm what is the radius?
radius=1/2 diameter so R=3cm
What is the diameter of a circle with radius r equals 36 in?
72, double the radius because radius is half of the whole diameter.
What is the formula for the surface area of a sphere with radius r equals 5?
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
What is the length of the radius if the circumference equals 18x3.14 for pie?
9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
Is the formula diameter equals 2 x r correct?
Yes it is, where r is the radius
An earthquake was felt throughout a circular of 1808.64 square miles what was the radius of the circular area?
Area, A, of a circle: A = (pi)r^2 r^2 = A/pi r = √(A/pi) r = √(1808.64/pi) r ≈ 23.9939 miles * so i would round it up and it would be 24miles * You can round the answer up to 24, but a radius 24 is not so close to the area which is 1808.64. Check: (pi)24^2 ≈ 1809.56, and (pi)23.9939^2 ≈ 1808.64
What is the radius if the circumference equals ten?
