If the area of a circle is 154m2 what is the circumference.

1 answer:

Sergeu [11.5K]2 years ago

6 0

The radius is found from

... A = πr²

... r = √(A/π) = √(154/π) m ≈ 7.00 m

The circumference is then

... C = 2πr = 2π(7.00 m) ≈ 43.99 m

The circumference is about 44.0 m.

7. (0,0)

8. (0,-4)

9. (0,5)

10. (0,0)

Step-by-step explanation:

there are 10 boxes in total, slope is y = mx + b

the slope is always the constant.

constant: number without a variable.

y - intercept:

y = mx + <u>b</u>

<u>if there is nothing after the slope it means the y -intercept is 0</u>
