The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
Start by finding the volume of the sphere. You know it's radius is 6cm. The volume of the sphere with respect to the radius is: v = 4/3πr3 So you can plug that radius in to get the volume: v = 4/3π(6cm)3 v = 4/3π216cm3 v = 288πcm3 We know that the volumes of the sphere and the cone are equal, and that the base radius of the cone is six centimeters. Using those, we can work out the cone's height. The volume of a cone is calculated as: v = πr2h we already have the volume and radius, so we simply have to rearrange that equation and solve for h v = πr2h h = v / πr2 and simply plug in our values: h = (288π cm3) / π(6cm)2 h = 288cm3 / 36cm2 h = 8cm So the height of the cone is eight centimeters
6cm + 6cm = 12cm
The answer depends on what the "6cm" refers to.
The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
6/2 = a radius of 3 cm
12 cm.
radius is half the length of diameter. So the radius will be 3cm. Thank you. Sharada
The formula for the circumference of a circle is C = 2πr, where C is circumference, π is pi (approx. 3.142), and r is the radius. So, for a circle with a radius of 6cm, C = 2(3.142)(6cm) = 18.852cm Rounding to the proper number of significant figures, this answer would be 20cm.
radius=1/2 diameter so R=3cm
12 cm
Since the diameter is always twice the length of the radius, the length of the radius is 6cm.
C = 2πr π = 3.142, r = 6cm C = 2(3.142x6)cm C = 41.04cm
6cm
The circumference of a circle = 2*pi*radius or diameter*pi
