A circular table top has a diameter of 90cm. Work out the area of the table top.


Sagot :

Answer:

Find the area of table top( circle)

A=πd²/4

A = 3.1415× (90cm)²/4

A= 3.1415× 8100cm²/4

A= 3.1415×2025

A=6361.5375cm²

The area of the table top is 6361.5375cm².

Area of a circle is pi*r^2

r is 90/2 = 45

pi x 45 x 45 = 6361.73
