Question

What is the best approximation of the area of a circle with a diameter of 17 meters?

Use 3.14 to approximate pi.


53.4 m²

106.8 m²

226.9 m²

907.5 m²

Answer 1

need help please

Answer 2

what do u think it is?

Answer 3

maybe 53.4

Answer 4

and how did u get that?

Answer 5

wouldn't it be like 3.14x17. Then what would that be?

Answer 6

i did that got 53.38 and my closes anser choose is 53.4

Answer 7

yes. Exactly good job

Answer 8

thanks

Answer 9

need help What is the best approximation for the area of this circle?

Use 3.14 to approximate pi.


12.6 m²

25.1 m²

50.2 m²

158.0 m²

Answer 11

which one do u think it is?

Answer 12

i did 3.14 times 4 so i think it is 12.56 i got for the times but the closes anser choose is 12.6m2

Answer 13

The formula for the area of a circle is: \[A = \pi r ^{2}\]
The diameter is given, 17.
The radius is half of the diameter.
So you would do:
\[\frac{ 17 }{ 2 }\]
which is equal to `8.5`.

Now, you can multiply and find the area.
\[A = (3.14)(8.5^{2})\]
\[A = (3.14)(72.25)\]
\[A = ~?\]

Answer 14

A=\[πr ^{2}\]=π·172≈907.92028
