C
Step-by-step explanation:
You would start by multiplying the radius by its self to get 9.6 * 9.6= 92.16 then you would mutiply that by pie 92.16 * 3.14 = 289.38 and you would round that to 289.4
Answer:
It would be -4
Step-by-step explanation:
a double negative becomes a + sign
So, -10 + 6=-4
Answer:
f(3) = -11, f(-7) = 19
Step-by-step explanation:
f(x) = -3x -2
1.
f(3) is the f(x) when x = 3 so where we see x in the equation we write 3 and calculate
f(3) = -3(3) -2 = -9 -2 = -11
2.
f(-7) = f( x= -7) = -3(-7) -2 = 21 -2 = 19
