What is the radius of a circle with a circumference 26 inches?
Circumference = pi x diameter Hence Diameter = Circumference/pi Here Diameter = 26/3.1415 = 8.276 And Radius = Diameter/2, so Radius is 8.276/2 = 4.138 inches
What is the constant term of 2x?
2x = 2x + 0 Hence the constant term is 0 (zero)
How many liters in a fish tank 600 x 1200 x 500?
1 liter is equal to 1000 cc (cubic centimeter) Hence Volume of tank = 600*1200*500= 360000000 cc hence 360000000 cc = 360000 liters
What is the HCF and LCM of 10 and 420?
divisors of 10 are 1,2,5 and 10, so highest number that can be divide 10 is 10,10 is also a factor of 420 Hence 10 is the highest common factor of 10 and 420. least multiplier of 420 is 420, also 420 is multiplier of 10 hence LCM is 420
The sum of the squares of two consecutive positive numbers is 85?
Let the numbers be m & m+1 (consecutive) Hence their squares are m^2 & ( m + 1)^2 => m^2 & m^2 + 2m + 2 Hence Their sum is m^2 + m^2 + 2m + 1 = 85 2m^2 + 2m - 84 = 0 m^2 + m - 42 =0 Factor (m + 7)(m - 6) = 0 Hence the numbers are 6 & 7 .
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
What is the radius of a circle with a circumference 26 inches?
Circumference = pi x diameter Hence Diameter = Circumference/pi Here Diameter = 26/3.1415 = 8.276 And Radius = Diameter/2, so Radius is 8.276/2 = 4.138 inches
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
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.
