I hope you can read this, and I hope you understand how I did 7. I probably overworked it, and it was possibly a simpler way to get it.
Answer:

Step-by-step explanation:
Surface area of cylinder = 2πr(h + r)
Volume of cylinder = πr²h
Given that S.A = Volume of the cylinder, therefore, we have:
2πr(h + r) = πr²h
Radius (r) is given as 2.5 cm
height (h) = x cm
Input the values and solve for x
2πr(h + r) = πr²h
2πr(h + r) = πr(rh)
2(h + r) = rh (πr cancels πr)


Subtract 2x from both sides


Divide both sides by 0.5

Answer:
(1436.8cm³) let me know if that helps
Step-by-step explanation:
-so if the diameter is a straight line and it's 15 cm
-The formula for the sphere it would be v=4/3πr³
-The radius is going to be r=7cm
-v = 4/3 π (7cm)³
-so you would type in 4/3 x 3.14 x 7 ³ =1,436
- 3.14 or π
- you would round it to the nearest 10th (1436.8cm³)
Answer:
111101011 subscript 2
Step-by-step explanation:
491 / 2 = 245 , 1 remainder
245 / 2 = 122 , 1 remainder
122 / 2 = 61 , 0 remainder
61 / 2 = 30 , 1 remainder
30 / 2 = 15 , 0 remainder
15 / 2 = 7 , 1 remainder
7 / 2 = 3 , 1 remainder
3 / 2 = 1 , 1 remainder
1 / 2 = 0 , 1 remainder
Now, we're going to put the remainders together in reverse order to get the final answer.
111101011 ---> this is the final solution
See the image below for how you would write 111101011 subcript 2.
