Question

Two calculations for the area of a circle are shown below. Select the correct calculation explain why you choose this calculation

Answer 1

solution 1
A= pie r squared
A = 3.14 (30^2)
A = 2,826 in ^2

Answer 2

solution 2
A = pie r squared
A = 3.14 (15^2)
A = 706.5 in ^2

Answer 4

give me a minute to figure it out

Answer 5

you need to pick the right solution then explain why you choose that one

Answer 6

Answer 20

okay

Answer 21

Okay so, first let me ask what do you think? a or b?

Answer 22

b

Answer 23

correct now basically the formula for this is a=pie r^2

Answer 24

the radius for this circle is 15 because 30 is the diamater so when you half that you get 15

Answer 25

yes i need to explain why i choose that calculation

Answer 26

now plug it in and you get A=3.14(15^2)

Answer 27

step by step

30/2 = 15 (finding the radius)
a=3.14(15^2) (plugging in the numbers)
now the one which matches with this is B

therefore, b is the correct answer!
