The diameter is six cm.
radius=1/2 diameter so R=3cm
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
The volume of a cylinder that has a radius of 3cm and a height of 7cm is 197.92cm3
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
The diameter is six cm.
radius=1/2 diameter so R=3cm
radius is half the length of diameter. So the radius will be 3cm. Thank you. Sharada
The perimeter of a circle is its circumference and it is: 2*pi*radius or pi*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.
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
If the radius of each tennis ball is 3cm, then the diameter of each ball would be 6 centimeters. And since there are 3 balls, the height of the cylinder would be 18 centimeters.
The volume of a cylinder that has a radius of 3cm and a height of 7cm is 197.92cm3
circumference = pi x diameter = 3.1416 x 3cm = 9.42cm (approx)
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
(3cm)2 x pi = 28.274 cm2
