Answer:
- About 28 cm³
Explanation:
The shape of a straw may be modeled by a cylinder; thus, use the formula for the volume of a cylinder with length (or height) 25cm and diameter 12mm.
Formula for the volume of a cylinder:
For the given straw:
- radius = diameter/2 = 12mm /2 = 6mm
- Convert to cm: 6mm × 1cm/10mm = 0.6cm
- height: 25cm
Substitute and compute:
Answer:
1. 3.14
Step-by-step explanation:
If we have
That just equals
For example, consider function
The inverse of that function is
So
If we compose the function, f(x) into f^-1(x).
We get
That proof of that.
1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14
2. We first find f(-7) which is -12,
We then find f(-12)= 5 so the answer here is 5.
