What is the area of the following circle

25pi or 78.50

Step-by-step explanation:

The equation for finding the area of a circle is pi(r)^2

We already know that the radius (r) of the circle is 5, and we are told that we can use pi or 3.14 as pi

Plug in 5 for r and square it, which leaves you with 25

Therefore the answer is 25pi, or if we simplify it further, 78.50

answer: it is 1: 47 pm

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
