Answer: 3-
Step-by-step explanation:
A) height of a cylinder: 7.96
b) height of come: 1.43
c) radius of cylinder: 4.07
d) radius of cone: 2.82
e) radius of sphere: 9
use the following formulas to solve:
a) volume= (pi)(radius^2)(height) and substitute what’s given
b) (1/3)(pi)(radius^2)(height) and substitute the given
c) volume= (pi)(radius^2)(height) and substitute what’s given
d) (1/3)(pi)(radius^2)(height) and substitute the given
e) volume= (4/3)(pi)(radius^2) and substitute the given
Answer:
Step-by-step explanation:
lets note a= chickens
b=cows
a+b=46
also = chickens has 2 legs, cow=4 legs
2a+4b=156..........we divide this equation by 2 so we can work with smaller numbers
a+2b=78 or we cam write a=78-2b
lets replace in the first equation a+b=46
78-2b+b=46
-b=46-78
-b=-32 multiply by -1
b=32
so we have 32 cows with 128 legs
a+32=46
a=14 chickens with 28 legs
It's 108°
A supplementary angle equals 180°
If one angle is 72°, the other would be 108°
