Answer:
236 cubic units (to 3 significant figures)
Step-by-step explanation:
volume of a cylinder = 
r²h (where r = radius and h = height)
Therefore, volume = x 5² x 3
= x 25 x 3
= 75
= 236 cubic units (to 3 significant figures)
Answer:
76
Step-by-step explanation:
Set it up with variables; tomatoes=t, sunflowers=s, corn=c
320=t+s+c
This year;
t=2s
c=t+40
so, replace 2s for t; c=2s+40
now we can put those factors in for 320=t+c+s
320= 2s+2s+40+s
(SIMPLIFY)---> 320=5s+40----> 5s+280----> s=56
now incorporate the s value into the other equations.
c=2s+40----> c=56(2)=40 ----> c=152
t=2s -----> t=2(56) ----> t=112
TOMATOES= 112 acres
CORN= 152 acres
SUNFLOWERS= 56 acres
To check your work: 320=t+s+c ----> 320=112+156+56
