A piece of string 25cm long goes exactly once around the edge of a plate in the form of a quadrant Calculate the area of the quadrant?
Presumably the plate is completely flat. The circumference will be 4*25 = 100 cm. First find the radius of the plate by rearranging the formula: 2*pi*radius = 100cm radius = 100/2*pi = 15.91549431 cm. Now use the formula pi*radius2 to find the area of the plate, and then divide your answer by 4 to give you the area of the quadrant. pi*15.915494312 = 795.7747155/4 = 198.9436789cm2. Therefore, the area of the quadrant is 199 cm2 correct to three significant figures.

How do you find the circunference of a bowl?
You get a string that can fit around the bowl and wrap the string around it and mark where they overlap. measure the string and there is the circumfrence!
How do you find the perimeter of a jigsaw puzzle using string?
You can find the perimeter of any planar (flat) object using string by wrapping the string around the outside of the object, noting the point on the string where you return to the starting point, and then measuring the length of that portion of the string.
How do you draw an ellipse?
Insert two pins [they become the two focal points] vertically into a piece of paper or two nails into the ground. Fasten two ends of a thread or string, making sure that when you are finished the loop of string will easily loop around the pins. Loop the string around the pins. Now take a pencil or marker and mark the ellipse out on your surface keeping the string taught.
There is a piece of string wrapped tightly around the earth How much longer would the string need to be if there was a gap of 1 meter between the string and the earth?
This is a minor geometrical calculation in which the radius of the object the string circles is irrelevant. If the radius of the Earth is 'r', then the length of the tight string = 2π(r) The increase of 1 metre is an increase of the radius to r+1, so the new length is 2π(r+1) If we give π a value of 3.1416, then the old length is the string was 6.2832(r) and the new length is 6.2832(r+1) or 6.2632(r) + 6.2632 So, as we don't put a value on (r), this actually means that if the string is around a pea or the earth the extra length needed to loosen it by 1 metre all around is 6.2632 metres and is the same in either case.
How do you calculate the circumference of a balloon?
Balloons are rarely (if ever) spherical, so you need to decide what you mean by its circumference.On possible way is to make a slip-knot noose with a piece of string. Slide the noose over the balloon, keeping the string tight. The noose will be opened to the extent of the balloon's circumference.
How to calculate string tension in a musical instrument?
To calculate string tension in a musical instrument, you can use the formula T F L, where T is the tension in the string, F is the force applied to the string, and L is the length of the string between the points where the force is applied. By measuring the force and length of the string, you can calculate the tension.
How do you calculate the tension in a string?
To calculate the tension in a string, you can use the formula T F L, where T is the tension, F is the force applied to the string, and L is the length of the string. This formula helps determine the amount of force acting on the string to keep it taut.
How do you calculate force in a string?
To calculate the force in a string, you need to consider the tension in the string. This tension can be calculated using the equation (T = F \cdot \cos(\theta)), where (T) is the tension, (F) is the force applied to the string, and (\theta) is the angle between the string and the direction of the force.
Calculate the check sum8 of hex string 0221323DA3B4?

How much is ice skating at Bristol ice rink?
How long is a piece of string? It depends what exactly you want and when you go, but around £7-£8 is probably about right.
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 find the circunference of a bowl?

How can one determine the tension in a string?
To determine the tension in a string, you can use the formula T F L, where T is the tension, F is the force applied to the string, and L is the length of the string. By measuring the force and length, you can calculate the tension in the string.

What is lanyard string called?
Gimp or Gymp don't know exactly how to spell it.
How to calculate the magnitude of the tension of a string?
The magnitude of tension in a string can be calculated using Newton's second law, which states that the sum of the forces acting on an object is equal to the mass of the object times its acceleration. In the case of a string under tension, the tension force can be calculated as the sum of all forces acting on the object connected by the string.
