Answer:

C

Step-by-step explanation:

Circumference Formula :

<u><em>Circumference = 2πr = πd</em></u>

<u><em /></u>

Solving :

⇒ 440 = 22/7 × d

⇒ d = 440/22 × 7

⇒ d = 20 × 7

⇒ d = 140 cm

frutty [35]

Answer:

The probability that he rolls a sum of 9 given the sample space is . 9/36, or 1/4.

What is the probability?

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

Ingredients for 7 cakes
lisabon 2012 [21]

Answer:

He made 5 cakes

Step-by-step explanation:

49 divided by 7 = 7

56 divided by 7 = 8

70 divided by 7 = 10

63 divided by 7 = 9

So for one cake you would need 7 g sugar, 8 g butter, 10 g flour, and 9 ml milk. So, 50 divided by 10 = 5 cakes

Use the arc length formula and the given information to find r. Show your work for full credit. s = 8.1 ft θ = (3.14/3)rad r = ?
VladimirAG [237]
This question is simple I'm a little confused on the specifics so I will try my best to help.

s=θ(r)
arc length = angle x radius
2.46888m(or 8.1 ft) = (π/3) x r
r =  (\pi /3)/2.46888
r = .425m
