Answer: radius = 3.61 cm
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Volume = 299 cm³
Height = 7.3 cm
Therefore,
299 = 3.14 × r² × 7.3
299 = 22.922r²
r² = 299/22.922 = 13.044
Taking square root of the left hand side and the right hand side of the equation, it becomes
r = 3.61 cm
Ok so you round 31 to 30 and 43 to 40 and then you multiply 30 by 40 and get 1200. 1200 is the same thing as 1200.00 bc you can take off the zeros after the decimal and it will be the same. Hope this helped and if your still confused you let me know I'll try to explain it more.
7 = 2n - 2
n= a number so twice a number is 2n and 7 is 2 less than twice this number.
