A right cone is 16 cm high the base radius is 12 cm. A cut is made through the cone 4cm from the vertex and parallel to the base. the discarded top is a right cone a base diameter of 6cm and slant?
Maroochie
sorry about that it would only let me write so much any way and a slant height 5cm. The part that remains is a frustum with slant height 15 cm. A hole with radius 3cm is drilled through the frustum, from the center of one base to the center of the other. the drilled frustum is then dipped into a vat of paint
a) sketch the original cone, the undrilled frustum, the discarded cone, the drilled frustuom. label all relevant measurements,
b) Caculate the exact area of the painted surfaceof the frustum. Explain the steps in your calculation procedure.

Is the diameter of a circle bigger or smaller then the radius?
The diameter is twice as long as the radius. d = 2r The diameter is basically a line through the center of a circle while a radius is from the center to the circumference of a circle.
Why is the radius of the circle half the diameter?
The radius of a circle is the distance from the centre to the rim. The diameter is the distance fron rim to rim passing through the centre point. It therefore follows that the radius is half the diameter
A CD has a radius of 6 cm Which is its diameter?
The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
Pi radius diameter?
Lets see: diameter is the longest line across a circle (goes through the center) radius is one half the diameter Pi is the ratio of the circumference to the diameter. (3.14159 .....)
How do you get the diameter from the radius?
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
What is the radius for a circle?
To know what a radius is you have to kno what a diameter is. The diameter is the distance accross a circle through its center. The radius is half the diameter.
What is the difference of diameter and a radius?
the radius is half of the diameter and radius is from the middle of the circle to the edge, whereas diameter is from one end to the other going through the middle.
How do you find tha radius?
The radius is half the diameter. Draw a line that passes through the centre of the circle and measure it. This is the diameter. Halve it and you will have the radius.
What is the relationship between the radius and the diameter?
The radius of a circle is half the length of the diameter. Scroll down to related links to find more about the diameter and the radius.
How is the diameter and radius similar?
diameter is 2 times the length of the radius and is a line straight through the center of the circle. radius is half of the diameter and is a line from the center to a edge of the circle
How do you find diameter when you have the radius?
The diameter of a circle is simply twice the radius of the circle. The radius is a line that starts from the center of the circle to the circumference of the circle. The diameter is a line that passes through the circle. diameter=2xradius
What is the radius of a circle with a 3cm diameter?
The radius would be HALF the diameter, making the answer 1.5cm ! The diameter of a circle is the distance across it, passing through the centre. The radius is the distance from the centre to the edge.
What is the difference in a radius and a diameter?
Radius is from the center of a circle to the outer edge. Diameter is from the outer edge to the opposite outer edge, i.e., through the center. The diameter has twice the length of the radius.
The radius of a circle is 1 inch. What is the circle's diameter?
The radius is the distance from the edge to the center. Diameter is distance from one edge through the center to the other edge. The diameter is twice the radius. If the radius is 1, then twice that is 2.
Is the diameter of a circle bigger or smaller then the radius?
The diameter is twice as long as the radius. d = 2r The diameter is basically a line through the center of a circle while a radius is from the center to the circumference of a circle.
Is a point a radius or a diameter?
No, neither. The radius is the distance from the center point of a circle to its edge. The diameter is the distance from one edge to the other that passes through the center point. The diameter is therefore twice the radius.
Why is the radius of the circle half the diameter?
The radius of a circle is the distance from the centre to the rim. The diameter is the distance fron rim to rim passing through the centre point. It therefore follows that the radius is half the diameter
