#### Relation of Radius Surface Area and Volume of a Sphere

In order to calculate Figure 1 shows the resulting graph of balloon radius vs height. As well as the Mooney-Rivlin model and the Gent model, the graph also includes a purely theoretical non-restoring model, in which the balloon exerts no restoring force at all (? p =0). The burst radius of the balloon is given by the manufacturer as 3.4m. This occurs at 27.5km for the non-restoring model

#### AP CALCULUS AB 2007 SCORING GUIDELINES College Board

The radius of a spherical balloon is 2 m and its volume is increasing at the rate of 0.1 m3 per minute. The volume V of a sphere of radius r is V=43?r^3.

Find the radius of the vase. Explain the method you would use to find the radius. 2.A design on the surface of a balloon is 5 cm wide when the balloon

#### How to find the circumference of a balloon? Yahoo Answers

You got one radius there and then you have another radius over there. We call this distance along the widest point of the circle, the diameter. So that is the diameter of the circle. It has a very easy relationship with the radius. The diameter is equal to two times the radius. Now, the next most interesting thing that you might be wondering about a circle is how far is it around the circle
