What is the circumference of a circle that has a radius of 10 in? Use 3.14 for π. 31.4 ft
62.8 ft
15.7 ft
314 ft

The circumference is 62.83in

Step-by-step explanation:

The formula to find the perimeter or circumference of a circle is P=2×π×r.

Step 1: Find the radius. In this case it is 10 in.

Step 2: Multiply the radius by 2 for simplicity. In this case 10×2=20.

Step 3: Multiply the last number by π. In this case, 20×3.14=62.8.

Step 4: You have the answer. Hope this helps!

i dont know i just need points

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
