Abuilding engineer analyzes a concrete column with a circular cross section. the circumference of the column is 18pi meters. what is the area a of the cross section of the column?

Answer

Circumference(C) of a circle is given by:

where r is the radius and value of

As per the given statement:

A building engineer analyzes a concrete column with a circular cross section.

The circumference of the column is meters.

then;

Divide both sides by we have;

9 = r

or

r = 9 meters

We have to find the area of the cross section of the column

Area of a circle is given by:

then;

meter square.

therefore, the area A of the cross section of the column is meter square.

how many players are there?

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
