Answer:
5 (not real answer)
Step-by-step explanation:
you solve it :)
I believe your answer is 615.44. The radius is 14 so you should multiply 14 by 14 and then multiply it by pi, which is 3.14. my apologies if that isn’t right but i’m pretty sure it is!
We need to write system of equations for this problem. Reading text we write 1 equation by 1.
first lets name our variables
x - Kiana cards
y - Gary cards
z - Monty cards
m - Willa cards
x = y-3 which we can write as y = x+3
z = x + 7
m = 2z
x + y + z + m = 74
I think easiest way to solve this is to express all variables in last equation and solve for x.
x + x+3 + x + 7+ 2x + 14= 74
5x = 50
x = 10
now we just calculate cards given to each friend
y = 13
z = 17
m = 34
