Answer:
91.7
Step-by-step explanation:
V = π x r² x h
V = π x 2² x (8-0.7)
V = π x 4 x 7.3

Answer:
36 cm2
Step-by-step explanation:
Hello there!
To find the volume of a rectangle (or cube) we do length x width x height. 6 x 6x 6 is 216. So, we know that the length, width and height are all 6 cm.
To find the area, we do length times width. 6 x 6 = 36 cm 2 is your answer!
I hope I helped you out! Have an amazing rest of your day!
If x-7 =0
Then x =7
Substitute x=7 into f(x):
2(7)^2 - 11(7) + k
= (98-77)+k
= 21+k
Therefore k=-21 because 21+(-21)=0
