The equation is given to compute A(7) = A(r) pi r²
7 = pi r²
r² = 7/pi
value of pi = 3.14
so,
r² = 7/3.14
r = √ (7/3.14)
r = 1.49
Well 9x40 would be the solution, so what is 9x40? That will be your answer.
Step-by-step explanation:
Total dogs and chickens = 14
If there are 10 dogs = 10 x 4 = 40 legs
If there are 4 chickens = 4 x 2 = 8
So 40 + 8 = 48
Answer:
8 bags
Step-by-step explanation:
You divided them by 20 which gives you 4. So you take the 3 and multiply by 4 which is 12 bags. And then you do the same for your bags which makes you do 2 times 4 which gives you 8. You take 20 - 12 and that leaves you with 8.
