A cylinder 90 cm high has a circumference of 20 cm A string makes exactly 6 complete turns round the cylinder while its two ends touch the cylinder's top and bottom how long is the string in cm?
For the string to wrap around the cylinder and yet do so by "coiling" around the outside of the cylinder from bottom to top, it will need to be 150cm long.
How do you write a algebraic expression for twice as long as the length of the string?
You can write 2X, where X is the length of the string.
What is the circumference of circles?
The circumference is the length of the outside of the circle. For example, if you took a piece of string and made a circle with it, then laid the string straight, the length of the string would be the circumference. The circumference of a circle can be measured by doing two times the radius of the circle times the mathematical constant, pi.
A piece of wire 16 m long is cut into two pieces so that one piece is three fifths as long as the other find the length of each piece?
one fifth is 3.2m. so one three-fifths piece is 9.6m and the two-fifths piece is 5.4m
What is the answer to this 32 inch board is to be cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 4 times as long as the first piece?
Let 1st piece be length x 2nd piece is 3x 3rd piece is 4x x + 3x + 4x = 32 8x = 32 x = 4 = 1st piece lenght 3x = 12 = 2nd piece 4x = 16 = 3rd piece
