Step-by-step explanation:
Answer:
They are already simplified..
Step-by-step explanation:
The area of a sector of a circle 'a' can be calculated using the formula a=πr²s/360, where 'r' is the radius and 's' is the angle measure in degrees. The rotation angle is the arc length in relation to the radius of the circle. This concept is part of mathematics introduced in high school.
The subject of your question is regarding the area of a sector in a circle. This is a mathematical concept usually introduced in high school level geometry. Here, the formula you've mentioned, a=πr²s/360, will enable you to calculate the area 'a' of a sector in a circle. 'r' represents the radius of the circle and 's' is the angle measure in degrees.
When we refer to rotation angle, we are talking about the arc length in relation to the radius of the circle. A full revolution of a circle is 360 degrees (°) which is equal to 2π radians. This is due to the definition of one radian as the angle when the arc length is equal to the radius of the circle.
To understand this, let's consider an example. If 's' is 90 degrees, and the radius 'r' is 1, then the area 'a' of the sector would be: a = π*1²*90/360 = π/4 square units.

What is (75 x 2) + (6-3)
Answer:
(75x2)+(6-3)
These equations are in parentesis so they happen first.
75x2=150. If we take 70 and multiply it by 2 we get 140. If we multiply 5 by 2 we get 10. So 140+10=150.
6-3 is next. That is common knowledge and we know its 3.
No we add 150+3=153 to get our answer.
Parenthesis first
Exponets after parenthesis
Multiplying going left to right
Divinding left to right
Adding left to right
Subtracting left to right
