Question

Rapunzel sees a flying saucer. The radius of the flying saucer is 18 feet. What is the area of the flying saucer using 3.14 rounded to the nearest tenth

Answer 1

`1017.4ft^(2)`

Explanation:

Area of a circle =
`\pi r^(2)`

However, the question wants to use 3.14 instead of
`\pi`.

Since the radius is given, which is 18 feet, we can plug and chug.

`A = 3.14*(18ft)^(2) \\A = 3.14*324ft^(2)\\A = 1017.36ft^(2)`

However, the question wants us to round it to the nearest tenth.

Therefore, the answer is
`1017.4ft^(2)`
