What is the radius of a cylinder with the volume of 375pi and height of 15 cm?
Vol = pi*r2*h so 375*pi = pi*r2*15 r2 = 25 so that r = 5 cm.
What is the remainder of 549 divided by 36 in 1 r2 form?
549/36 = 15 r9
How do you calculate the radius of a sector with an angle of 1.5 radians and 15cm. I have tried but I only ever get the answer of 10 or 2squareroot10 and the right answer is 2squareroot5?
To produce the required answer, the question should state, "How do you calculate the radius of a sector with an angle of 1.5 radians and an area of 15 sq cm ?If an angle of 1.5 radians sweeps out an area of 15 sq cm then this is proportional to an angle of 2π radians sweeping out the area of the circle, namely πr2.1.5/2π = 15/πr2 : 1.5/2 = 15/r2 : r2 = (2 x 15)/1.5 = 30/1.5= 20If r2 = 20 then r = √20 = √(4 x 5) = 2√5
What is r2 when measuring the volume of a cylinder?
r2 (r2) refers to the radius of the cylinder squared.
How do you find the surface area of a sphere with a radius of 15 inches?
Use this formula (Ï€ = Pi): Surface area = 4Ï€r2
What is the radius of a cylinder with the volume of 375pi and height of 15 cm?
Vol = pi*r2*h so 375*pi = pi*r2*15 r2 = 25 so that r = 5 cm.
If a cylinder has a height of 56 meters and the volume if 9891 cubic meters what is the diameter of the base?
volume = pi * r2 * h 9891 = 3.14 * r2 * 56 9891/56 = 3.14 * r2 * 56/56 176 = 3.14 * r2 176/3.14 = 3.14/3.14 * r2 56 = r2 7.5 = r 15 = d 15 meters is the diameter
Equation x2 plus Bx plus c equals 0 has 5 as the sum of its roots and 15 as the sum of the squares of its roots The value of 'c' is equals?
x2 - (-b/a)x + (c/a) = 0 or x2 - (sum of the roots)x + (product of the roots) = 0 Let the roots be r1 and r2. So we have: r1 + r2 = 5 (r1)2 + (r2)2 = 15 r1 = 5 - r2 (express r1 in term of r2) (5 - r2)2 + (r2)2 = 15 25 - 10r2 + (r2)2 + (r2)2 = 15 2(r2)2 - 10r + 25 = 15 (subtract 15 to both sides) 2(r2)2 - 10r + 10 = 0 (divide by 2 to both sides) (r2)2 - 5r + 5 = 0 (use the quadratic formula) r2 = [-b + &- sq root of (b - 4ac)]/2a r2 = {-(-5) + &- sq root of [(-5)2 - 4(1)(5)]}/2(1) = [5 + &- sq root of (25 - 20)]/2 = (5 + &- sq root of 5)/2 r1 = 5 - r2 r1 = 5 - (5 + &- sq root of 5)/2 Thus, when r2 = (5 + sq.root of 5)/2, r1 = (5 - sq.root of 5)/2 or vice versa. Since the given equation is x2 + bx + c = 0, a = 1, then c equals to the product of roots. So that, c = (r1)(r2) = [(5 - sq.root of 5)/2][(5 + sq.root of 5)/2] = [52 - (sq.root of 5)2]/4 = 5
