11-12 Significant Figures in Geometry Use geometric formula on the inside front cover of the book to solve these problems.

12 Find the volume of a cone whose height is 52.3 cm and whose radius is 4.267 cm .

To determine

The volume of the cone.

Explanation

Given:

The height of the cone is 52.3cm.

The radius of the cone is 4.267cm.

Approach:

The formula for volume of the cone is,

V=13πr2h...(1)

Here, V is the volume, r is the radius of the cone and h is the height of the cone.

The significant figures in a number are one from first nonzero digit to the last nonzero digit when reading from left to right.

When multiplying or dividing, round off the final result so that it has as many as significant digits as in the given values with the fewest number of significant digits.

Calculation:

Substitute 4.267cm for r and 52
