Answer (1 of 6): First, we need to find the volume in term of the radius: V=frac{4}{3}pi r^3 Then we do the derivative of t on both sides: frac{dV}{dt}=4pi r^2frac{dr}{dt} frac{dV}{dt} is -10 because it's decreasing. r=4+2=6, radius of the iron ball plus thickness of ice at that instan...

But the golf ball diameter on the British side of the sport is 1.62 inches. Let me explain why. Golf rules in Europe fall under the control of R&A, not USGA. So this makes way for some discrepancy. This slight difference in the golf ball diameter is due to a simple reason. And that is, playing conditions in Europe are chillier and windier.

We know the ball surface area formula now. As an example, the surface area of a ball with a radius of 10 cm can be found below: A = 4πr 2. A = 4π * 10 2 = 1256.64 cm 2. Now you know how to find the surface area of a ball. If you need a handy calculation tool to find the surface area of a ball, try out our ball surface area calculator.

A solid metallic cone of height 10 cm, radius of base 5 cm is melted to make spherical balls each of 2 cm diameter. How many such balls can be made? Volume of a cone = 1/3*22/7*r^2*h where r is the radius of the cone and h is its height. Volume of the solid metallic cone = (1/3*22/7*5*5*10) cm^3 Volume of a sphere = 4/3*22/7*R^3
