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 roun

Vladimir79 [104]

Answer:

$1017.4ft^{2}$

Step-by-step 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 $1017.4ft^{2}$
