Answer:
6358.5 sq. cm
Step-by-step explanation:
In this problem, we need to find the area of the circular table.
The table is said to be circular, so we should use the area formula of a circle.
Given its diameter, using the area formula of a circle in terms of diameter is appropriate here; A = πd²/4
Let us plug in the length of diameter:
A = π(90 cm)²/4
A = 3.14(8100 cm²)/4
A = 25434 cm²/4 = 6358.5 sq. cm
