Area of circle = πr²
1075.21 = πr²
1075.21/π = r²
r = √1075.21/π
r = 18.5
The area of the sector with a radius of 20 units and a central angle of 162° is 180π unit².
<h3>What is the sector of a circle?</h3>
A sector is the portion of a circle enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger is the major sector.
The radius of the sector =20 units
Central angle subtended by sector = 162° = 162π/180 radians
As we know the area of a sector= 0.5r²α
where r is the radius and α is the central angle.
So, the area of the given sector = 0.5*20²* 162π/180
The area of the given sector = 180π unit²
Therefore, The area of the sector with a radius of 20 units and a central angle of 162° is 180π unit².

Answer: Plan B
Step-by-step explanation:
First you would find out how much they have to pay the monthly fee in 5 months. Plan A pays $50 in 5 months and Plan B pays $30 in 5 months
Then you find he amount of money that they need to pay for a hundred texts. Plan A spends $25 and Plan B spends $35 .
Then you add the numbers together and Plan A you would pay $75 and Plan B you would spend $65
Answer:
greater
Step-by-step explanation:
45.5 + 3.21 = 48.51
48.51 is greater than 48 by 0.51
