Answer:
Step-by-step explanation:
radius = d/2=22/2=11
area=pi*r*r=22/7*11*11
=380.28
Nope if you round the first number to 2000 and the second to 300 you should expect around 600000 which is not the case.
Answer:
c tomato 2.5
pepper = 3.5
Step-by-step explanation:
Let t= the price of tomato plants
p =the price of pepper plants
3t+ 4p = 21.50
5t+ 2p = 19.50
Multiply the second equation by -2
-10t -4p =-39
Add this to the first equation to eliminate p
-10t -4p =-39
3t+ 4p = 21.50
---------------------
-7t = -17.5
Divide by -7
t = 2.5
Now find p
5t+ 2p = 19.50
5( 2.5) + 2p = 19.50
12.5+2p = 19.50
Subtract 12.5 from each side
2p =7
p =3.5
We want the price of 1 tomato and 1 p
3.5+2.5
160 is the answer after solving.
Hope you understand the working.
The answer rounded up is 2691
