D 115
2 answers:
We will be using PEMDAS rule here :
P
- Parentheses first
E
- Exponents (ie Powers and Square Roots, etc.)
MD
- Multiplication and Division (left-to-right)
AS
- Addition and Subtraction (left-to-right)
8+2(12-5)
Step 1:
Solving parenthesis first:
8+2(7)
Step 2:
Multiplying 2*7
8+14
Step 3:
Adding 8 and 14
22
Answer is 22
we are given
![8+2(12-5)](https://tex.z-dn.net/?f=%208%2B2%2812-5%29%20)
we can use
P: Parenthesis
E:Exponent
M: Multiplication
D: Division
A: Addition
S: Subtraction
so, firstly we will find parenthesis value
![=8+2*7](https://tex.z-dn.net/?f=%20%3D8%2B2%2A7%20)
now, we can multiply
![=8+14](https://tex.z-dn.net/?f=%20%3D8%2B14%20)
now, we can add

Answer: 6π
<u>Step-by-step explanation:</u>
Area of a circle is π r².
Area of a section of a circle is π r² × the section of the circle.
![A=\pi r^2\bigg(\dfrac{\theta}{360^o}\bigg)](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%5Cbigg%28%5Cdfrac%7B%5Ctheta%7D%7B360%5Eo%7D%5Cbigg%29)
Given: r = 6, Ф = 60°
![A=\pi (6)^2\bigg(\dfrac{60^o}{360^o}\bigg)\\\\\\.\quad =\pi (6)^2\bigg(\dfrac{1}{6}\bigg)\\\\\\.\quad =6\pi](https://tex.z-dn.net/?f=A%3D%5Cpi%20%286%29%5E2%5Cbigg%28%5Cdfrac%7B60%5Eo%7D%7B360%5Eo%7D%5Cbigg%29%5C%5C%5C%5C%5C%5C.%5Cquad%20%3D%5Cpi%20%286%29%5E2%5Cbigg%28%5Cdfrac%7B1%7D%7B6%7D%5Cbigg%29%5C%5C%5C%5C%5C%5C.%5Cquad%20%3D6%5Cpi)
