Answer:
4.44 cm²
Step-by-step explanation:
If the diagram attached below is required to complete the question,
Applying,
Area of the shaded segment(A) = Area of the sector- area of the triangle
A = (πr²∅/360)-(r²sin∅/)2................ Equation 1
Where r = radius of the circle, ∅ = angle at the center of the circle,π = pie
From the question,
Given: r = 5.4 cm, ∅ = 72°
Constant: π = 3.14
Substitute these values into equation 1
A = (3.14×5.4²×72/360)-(5.4²/2×sin72)
A = 18.31-13.87
A = 4.44 cm²
There are three students. The student in front has 2 students behind them, the student in the back has 2 students in front of them, and there is a student in the middle.
Answer:
A. (2, 7), (1, 4)
Step-by-step explanation:
The first equation tells you that y cannot be negative. (Both terms are positive.) So, the only viable answer choice is A.
Answer:
Yes.
Step-by-step explanation:
The radius in the formula for a volume of a cylinder is squared so yes the volume would be higher, but it depends on the height as well.
Formula - V = πr²h
It would take 16.7 days for the population to double. This is near 17, so 17 would be the best answer.
I hope this helps!
