Answer:
8.3 cm
Step-by-step explanation:
1. Find the volume of the small cylinder (volume of a cylinder = πr² · h)
π(4.5²) · 17 = 1080.945 cm³
2. Set up the equation to find the volume of the big cylinder
πr² · 5 = 1080.945
3. Divide both sides by 5
πr² = 216.189
4. Divide both sides by π (3.14)
r² = 68.85
5. Square root both sides
r = 8.3 cm (rounded to the nearest tenth)
Answer:
x = 7
Step-by-step explanation:
Just try all the choices and see which one gives a valid answer
4x+7≥35
x = 6
: 4 (6) + 7 = 31 is NOT ≥35 (not valid)
x = 7 : 4 (7) + 7 = 35 IS ≥35 (valid) (ANSWER)
x = 3
: 4 (3) + 7 = 19 is NOT ≥35 (not valid)
x = 0
: 4 (0) + 7 = 7 is NOT ≥35 (not valid)
Answer:
3
16÷5=3.2
don't @ me if I'm wrong, I'm sorry
H=3 because 27 divided by 9 is 3
