5. Triangle PQR with vertices P(-2, 3), Q(2, 4),
and R(1,-1) in the line x = -3.

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
