Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
What is the Circumference of a circle whose diameter is 56cm?
circumference = pi*56 = 175.929 cm to 3 dp
How do you find the diameter of a circle with the perimeter?
The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.
Perimeter of a semicircle when the Diameter is 8?
Perimeter of a semicircle is the length of the half-circle plus the diameter. The whole circle would have a length of diameter times pi, but since it's only half... Perimeter of semicircle = (1/2*pi*D) + D
What is difference between a radius and a diameter?
Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.
Is 56cm a perimeter or area?
It must be a perimeter. An area measurement would a square measurement like 56cm². ■
What is the radius of a circle with the diameter of 56 centimeters?
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
What is the perimeter of a right traingle with the legs of 24cm and 7cm?
Use Pythagoras' theorem to find the hypotenuse which works out as 25cm Perimeter = 25+24+7 = 56cm
How do you find the perimeter from the diameter?
The perimeter or circumference of a circle = diameter times pi
What is the perimeter of a circle if the diameter is 20 ft?
The perimeter is the diameter times pi. So the perimeter is 20pi ft
A garden roller has a diameter of 56cm and 70cm wide it is pushed that it revolves 20 times what distance has it traveled?
The width is not needed as the distance travelled is 20 times its circumference (= {pi} x diameter): distance = 20 x {pi} x 56cm ~= 3519cm = 35.19m
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
What is the Circumference of a circle whose diameter is 56cm?
circumference = pi*56 = 175.929 cm to 3 dp
How many times will the wheel of a car rotate in a journey of 88km if the diameter of the wheel is 56cm?
50,020 times
Find the perimeter of a circle if the diameter is 36 centimetres?
Perimeter = pi*diameter = 113.1 cm
What happens if you double the diameter of a circle?
You get 2 circles of diameter. If you were trying to find a perimeter, Never double the diameter. If you have a radius, You have to double it to get a perimeter.
Are diameter and perimeter equal?
No
