Answer: C≈628.32
Step-by-step explanation: This is due to the fact that the formula to find the circumference would be C=2πr which in this case the raduis would be 100 because if u divide the diameter by 2 u get 100. Now the formula is 2*3.14*100
Answer:
x = 2, -2, -1/5
Step-by-step explanation:
g(x)= 5x^3+x^2-20x-4
g(x)= x^2(5x+1)-4(5x+1)
g(x)=(x^2-4)(5x+1)
g(x)=(x-2)(x+2)(5x+1)
x-2=0
x= 2
x+2=0
x= -2
5x+1=0
x= -1/5
x=14
