Circumference of the circle (18 cm) = 2*pi*radius
Rearrange the formula:
radius = Circumference/2*pi
radius = 2.864788976 cm or 3 cm to the nearest cm
height = 44 cm

What is the lateral area of cylinder?
Lateral Area= (2pi)x(radius)x(height) Try imagining that you take the lateral area and unfold it from the cylinder. If you imagine it correctly you get a rectangle. The height of the cylinder is the height of the rectangle. Then the circumference is the length. SO you multiply the circumference of the base times the height.
How is the formula for finding the lateral area of a cylinder like the formula for finding the area of a rectangle?
L.A.= 2*pi*radius*height its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
The area of rectangle?
Rectangle area = (rectangle width) x (rectangle height)
What is the height of a cylinder with the diameter of 8?
The diameter of a cylinder is not related to its height. A cylinder with a diameter of 8 can have any height. Also, don't measure geometric figures without using a unit of measurement. A diameter is 8 something, it could be 8 centimeters, 8 inches, 8 miles, and so forth, it is not just 8.
2 cylinder radius 6 cm height 10 cm?
603.2 cm2 haha just did the assignmentUnit 2: Geometry and Measurement
How do you derive of surface area of cylinder?
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!

How do you find the length of a rectangle around a cylinder?
find the circumference of the circle and multiply it by the height of the cylinder
What is a closed figure that has two basic units of measurement?
A rectangle. Height and width.
How do you find out the measurement of the perimeter of a rectangle?
2*(base) + 2*(height) = perimeter
Can you find the exact measurement of a cylinder?
What do you mean by "exact measurement"? Do you wish to determine the cylinder's height? Its diameter? Its surface area? Its volume?
What is is the lateral area?
Lateral Area= (2pi)x(radius)x(height) Try imagining that you take the lateral area and unfold it from the cylinder. If you imagine it correctly you get a rectangle. The height of the cylinder is the height of the rectangle. Then the circumference is the length. SO you multiply the circumference of the base times the height.
How do you find the area of 1 face of a cylinder?
Faces of cylinder are circular therefore area must be pi*radius*radius That is the formula for the top and bottom faces, the circles. However, the main face, the face connecting the two circles, is really a large rectangle bended to fit with the circles. The height of the rectangle is the same as the height of the cylinder. The width of the rectangle is the circumference of the circle (pi * 2 * radius). The formula for a rectangle is width * height. So, the side face is height of cylinder * circumference of circle (pi * 2 * radius.)
How do you draw a net for a three dimensional figure and the figure is a right circular cylinder?
Draw a rectangle for the side of the cylinder and on top and bottom of this rectangle 2 circles for the base and the top of the cylinder The rectangle width would be the diameter of the circle large and the same height that the cylinder
What is the surface area of a cylinder if the radius is 7 and the height is 17?
Split the cylinder into two circles and a rectangle to find your answer.
What measurement represent the volume of a cylinder?
Volume of a cylinder in cubic units = pi*radius2*height or length
What shape would be the side view of a cylinder?
A rectangle. If the cylinder has the same height as its width, the side view would be a square.
