Answer:
2A/r + 2r
Step-by-step explanation:
A sector is made of an arc and two radii. As such, the perimeter of the sector is the sum of the length of an arc and the two radii. Given that the radius is r and the area is A, the area of a sector A
= Ф°/360° * πr²
The length L of an arc of the sector
= Ф°/360° * 2πr
Hence,
A/L = r/2
L = 2A/r
The perimeter of the sector
= L + 2r
= 2A/r + 2r
Answer:
LINEAR
Step-by-step explanation:
Look at the y-values. As x increases, y increases each time by 9 units.
This indicates an arithmetic progression. The function is LINEAR.
I think the answer is 2010
To find out the answer of this question, you just need to find out the difference between beginning amount and the ending amount
