Answer:

d = 10 km

Step-by-step explanation:

Circumference is equal to pi times diameter

C = pi *d

We know the circumference is 30

30 = pi *d

Let pi = 3

30 = 3d

Divide each side by 3

30/3=3d/3

10 =d

The diameter is 30 km

The answer is 10 as the diameter because it says to estimate pi as 3. Since we know the circumference is 30 we can reverse it to find the diameter, since Circumference is pi time diameter.

butalik [34]

Who's Weggy?

2x + 3y = 40

-2x + 2y = 20

These are set up so we can just add them for the solution:

5y = 60

y = 12

2y-20=2x

x=y-10=2

Answer:

m<A: 62

m<B: 54

Step-by-step explanation:

180 - 116 = 64

3x - 13 + 2x + 4 + 64 = 180

5x + 55 = 180

5x = 180 - 55

5x = 125

x = 25

m<A:

3x - 13

3(25) - 13

m<B:

2x + 4

2(25) + 4
