$($b$)$ Using the highest load calculated from question $22,$ calculate the required area of the circular

shape made of concrete if it is a pier or a column with a compression force acting on it$.$ What is

the radius of this circle? The maximum compressive strength of this concrete is $34473786$ pascals.

Use the following equations to complete the problem. Show all work and calculations.

Highest ultimate load $=($max$.$ compressive strength$)($cross$-$sectional area$)$

Cross$-$sectional area of circle $=x($ radius ${)}^2$

$=3\mathrm{.}14$

Highest ultimate load $=($max$.$ compressive strength$)($cross$-$sectional area$)$
