Answer:
Volume of the roll = 3,817.04 cm³
Step-by-step explanation:
The diagram of the roll of the tissue paper given is a model of two cylinders:
✔️Bigger cylinder with diameter (d) of 14 cm and height of 27 cm
✔️ Smaller/inner cylinder with diameter (d) of 4 cm and height of 27 cm
Thus:
The Volume of the roll = volume of bigger cylinder - volume of smaller cylinder
✔️Volume of bigger cylinder = πr²h
r = ½(14) = 7 cm
h = 27 cm
Volume of bigger cylinder = π*7²*27
= 4156.33 cm³
✔️Volume of smaller/inner cylinder = πr²h
r = ½(4) = 2 cm
h = 27 cm
Volume of smaller/inner cylinder = π*2²*27
= 339.29 cm³
✅The Volume of the roll = 4156.33 - 339.29 = 3,817.04 cm³
Answer:
a = 2
b = 3
c = 2³ or 8
Step-by-step explanation:
Exponent Rule:
log₂(4) = 2 or 2² = 4
2⁵/2² = 2³
2³ = 8
