Answer:

The circumference is 24.69 in.

The area is 48.52 in.

Step-by-step explanation:

  • Circumference rule => Cf=2πr

So, Cf=2π(3.93)=24.69in

  • Area rule => A=πr^2

So, A=π(3.93)^2=48.52in

92 cm

Step-by-step explanation:

Look at the attached photo, it may give you a better understanding

can someone please do this for me and tell me how so I can do the other one pleaseeee I don't know what to do
KonstantinChe [14]

Answer:

P(green) =1/4

P(orange)=1/2

Step-by-step explanation:

I'm assuming this is probability but it\s been a while, so i'm not sure

number one is a square being divided into half and then one half is being divided into quarters. (as shown by the dotted lines and right angle)

so the probablity of landing in green is 1/4, because it is one fourth of the square.

the probability of the orange is 1/2 because it is 1/2 of the square

The same logic would apply to the "circle" i can see in the next problem. 120 degrees is 1/3 of 360, 90 is 1/4, and so on.

Hope that helps.

Show me how to solve 172 times 6
stepan [7]

I would recommend starting by turning 172 into 100+70+2. This makes it much easier to multiply it by 6.

(100+70+2) × 6 =

distributive property

(100×6) + (70×6) + (2×6) =

Simplify

600 +  420 + 12 =

Add it all together

1032

The answer would be 1032.
