Answer:
r = 8 ft
Step-by-step explanation:
The formula for circumference of a circle is
C = 2 * pi *r
We know the circumference is 16 pi
16 pi = 2 pi r
Divide each side by 2pi
16 pi /2 pi = 2 pi r / (2pi)
8 = r
Answer:
Step-by-step explanation:
4x+2y = -24 -------------(i)
<u> -4x+y = 12 -</u>------------(ii)
add (i) &(ii) 3y = -12
y = -12/3
y = -4
Put y = (-4) in (i)
4x + 2*(-4) = -24
4x - 8 = -24
4x = -24 + 8
4x = -16
x = -16/4
x = -4
The answer is 16.8. Tell me if I'm right
