I really need help, someone please help me
Hoochie [10]

Answer:

18.84 meters.

Step-by-step explanation:

The formula for a circle is πr^2.

πr^2 = 28.26

3.14 * r^2 = 28.26

r^2 = 9

r = plus or minus 3.

But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters.

The formula for the circumference is 2πr.

2 * 3.14 * 3 = 6 * 3.14 = 18.84.

So, the circumference of the circle is 18.84 meters.

Hope this helps!

Yo can someone do this for me ty i’m too lazy to do this myself
Debora [2.8K]

Answer:

1. 8 + 4 = 12 x 6 = 72

2. 9 + 6 = 15 x 4 = 60

3. 11 + 8 = 19 x 6 = 114

4. 4 + 6 = 10 x 5 = 50

5. 7 + 3 = 10 x 8 = 80

6. 8 + 12 = 20 x 9 = 180

7. 5 + 10 = 15 x 8 = 120

8. 19 + 13 = 32 x 10 = 320

9. 3 + 6 = 9 x 2 = 18
