F(r) = 3.14r2 . What is f(3)?

lbvjy [14]

Answer:

The value of f(3) = 28.26

Step-by-step explanation:

You have to do is to substitute r = 3 into the function :

$f(r) = 3.14 \times {r}^{2}$

$f(3) = 3.14 \times {3}^{2}$

$f(3) = 3.14 \times 9$

$f(3) = 28.26$

Is (-3, -2) a solution to the equation y = -2x + -8?

denis23 [38]

Answer:

(-3, -2) is a solution of y = -2x + -8

Step-by-step explanation:

y = -2x + -8

(-3, -2) are the coordinates of P(x,y)

-2= -2(-3) - 8

-2 = +6 - 8

-2 = -2

Since LHS = RHS, (-3, -2) is a solution of y = -2x + -8
