The volume is: 301.6 cm3
The circumference of a circle if the diameter is 12cm is 37.7cm
Close to 12cm
The diameter is twice the radius and so it is 24cm
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
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.
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
The circumference of a circle if the diameter is 12cm is 37.7cm

The lateral surface area is 565.49cm2
12pi cm
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
To calculate the volume, multiply the length x width x height. volume = 12cm x 6cm x 4cm = 288cm3
22.80cm (rounded to two decimal places.
12cm x6cmx4cm=288cubic centimeters
It's the same as a rectangle with a lenght of 12pi and a width of 13 cm. Therefore it equals to 12x13pi = 452 squared cm But btw, that is not possible since the diametre is greater than the slant... It can't be a cone.
