—radius is 1/2 the diameter so if the diameter is 6, the radius would be 3.
—the circumference is 2pier
so you would use your calculator and use the pie symbol or 3.14 and multiply 2*3.14*3 (3=radius for my example)
— the area is pie r^2
so you would multiply 3.14*3 squared

Answer:

Required equation: 366=x-30

Length of the main span of the Dames point Bridge = 396 meters

Step-by-step explanation:

Main span of the Sunshine Skyway Bridge = 366 meters        .... (1)

Let x represent the length of the main span of the Dames point Bridge.

It is given that the bridge's main span is 30 meters shorter than the main span of the Dames Point Bridge.

Main span of the Sunshine Skyway Bridge = x-30 meters     .... (2)

From (1) and (2) we get

366=x-30

Add 30 on both sides.

366+30=x-30+30

396=x

Hence, the required equation is 366=x-30 and the length of the main span of the Dames point Bridge is 396 meters.
