Alarge planetarium in the shape of a dome is being built. when it is complete, the base of the dome will have a circumference of 87 kilometers. what area of land was required for this planetarium?

602.32 km²

Step-by-step explanation:

First, find the radius of the circle using the circumference formula

C = 2π*r

87 = 2π*r

∴ r = 13.8465 km

Second, using the radius, calculate the area:

A = π * r²

A = π * 13.8465²

A = 602.32 km ²
