Problem:

A cruise ship has a large, circular window. It has a diameter of 8 meters. What is the window's area​.

Solution:

D = 8m

r = D/2

r = 8/2 = 4m

A = πr²

A = 3.14(4)²

A = 3.14(16)

A = 50.24m²

Answer:

Formula of the area of a circle: v=πr^2

diameter: 8, so the radius is 4(since half of diameter is a radius)

Solution:

v=πr^2

v=π(4^2)

v=π(16)

v=50.24m^2

Therefore, the window's area is 50.24m^2.

Hope it helps :)
