Answer:
Yes, they should.
Step-by-step explanation:
If she is using the data from her table to graph her function they should represent the same function.
Answer:
volume: 1500 , surface area: 764
Step-by-step explanation:
formula of circle's area

formula of cylinder's surfaces area

Let x be the time she ran and y be the time she walked
then distance ran = 25x and distance walked = 5y
so 15x + 5y = 42
and x + y = 4
* second equn. by -5:-
-5x - 5y = -20
add this to the first equn:0
10x = 22
x = 2.2
distance she ran = 2.2 * 15 = 33 km
Area of a circle is: (pi)(r)^2
If diameter is 6, then radius is 3.
(pi)(3)^2
Area= 9(pi) or 28.26
Circumference is: 2(pi)(r)
2(pi)(3)
6(pi) = 18.84
