What is the radius of a circle with a circumference 26 inches?
To find the radius of a circle with a given circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 26 inches, you can plug this value into the formula and solve for the radius. Dividing the circumference by 2π gives you the radius of the circle, which in this case is approximately 4.14 inches.
What is the area of a circle 22 inches in diameter?
The general eq'n for a circles area is A = pi r^(2) Hence With a diamter of 22 inches . the radius(r) is half the diameter at 11 inches. Substituting A = pi 11^(2) A = 121 pi Using pi = 3.14 Hence A = 121 X 3.14 A = 379.94 sq.ins. (NOT ins^(2))
What is the diameter of a 3000 sq ft circle?
Remember A = pi r^2 Hence 3000 = pi r^(2) r^(2) = 3000 / pi ( =3.14) = 954.92965... sq.ft. r = sqrt(954.92965... ) = 30.90193616 ft. Now remember the diamter(d) is twice the radius(r) d = 2r Hence d = 2(30.90191616...) = 61.80387232... ft. d =~= 61.8 ft.
Circle diameter of 2.5 what is the circumference?
Remember and comit to memory the two circle equations. C = pi d = 2 pi r & A = pi r^(2) Taking the first equation C = pi d d = 2.5 pi = 3.141592..... ~ 3.14 Hence C = 3.14 * 2.5 C = 7.85 units.
What is the diameter of a circle if the circumference is 52 pi?
Remember the circle eq'n C = pi*d Algebraically rearranging d = C / pi Hence d = 52 pi / pi Cancel down by 'pi' Hence d = 52.
What is the radius of a circle with a 76in diameter?
The radius is one-half of the diameter. Hence, the radius of a 76 in diameter circle is 38 in.
If the radius is 10 yards the diameter will be what?
Diameter is double the radius; hence, it is 20 yards in this example.
What is the diameter of a circle whose radius is 53?
The diameter of any circle is twice the radius. Hence, for this particular circle, the diameter is 106.
If the radius of the moon is 1737.4 kilometres what is the diameter of the moon?
A radius is always half the diameter. Hence the diameter is 2 times 1737.4. That's 3474.8 km
How do you find the diameter if you have the area of a circle?
Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.
What is the circumference of the circle if the diameter is 24 meter?
half of a diametre is radius. hence multiply the diameter by 0.5 then use the formular of cicumference, which is 2*pie*r
What is the radius of a circle with a circumference 26 inches?
To find the radius of a circle with a given circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 26 inches, you can plug this value into the formula and solve for the radius. Dividing the circumference by 2π gives you the radius of the circle, which in this case is approximately 4.14 inches.
If you have a diameter of 8 what is the radius?
Four - Diameter is the length of the circle, one end to the other through the cirle, while radiusis from the middle of the circle , out. Hence Being half. s :)
Why should you use a convex lens of large radius of curvature in performing newtons ring experiment?
Radius of rings is directly proportional to the square root of the radius of curvature. Thin lens would have larger radius of curvature and hence the option
How do you calculate the volume of a sphere when you are given the diameter?
volume of a sphere is 4/3 pi x r^3 or, 4/3 x 3.142 x r ^3 r, or radius would be 1/2 the diameter, hence r ^3 would come to (d^3)/8 Solved :-)
What is the area of a circle 4.6 inches wide?
Assuming by 'width' you mean diameter. A = pi r^2 Where 'r' is the radius. The radius is half of the diameter. So 4.6 / 2 = 2.3 ins. is the radius (r) Hence A = 3.141592.... X 2.3^2 A = 3.16.619 sq. ins141592... X 5.29 A = 16.619 sq.ins
If a circles radius is 20 inches what is the circumference?
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
