Answer:
12.5664 units (rounded off to four decimal values)
Step-by-step explanation:
Arc length = 2 × π × r ×
For our partial circle;
The radius (r) = 8 units
The central angle = 90°
Arc length = 2 × π × 8 × = 12.5663706144 units
Or 12.5664 units (rounded off to four decimal values)
The answer of the following subtraction is 5
Step-by-step explanation:
As per the question the equation will be
To find the subtraction,
The steps are as follow
=
=1-2 +
[ we took the variables with same power together]
=5
Hope it helps you.
For this problem, we are going to have to use our order of operations, which is: Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction (often abbreviated PEMDAS).
First, let's see if there are any parentheses. There is one set of parentheses which we will have to remove. To do this, we will simply multiply the -4 by the 6, given us a value of -24 to take the place of the -4(6). Now our problem is:
Next, we will check for exponents. There are exponents, so we will need to take care of those. is equal to 144, and
is equal to 121. We can now substitute these values into the original expression to get:
Now, we will check for any multiplication or division. Besides the entire expression (which is a fraction), there is none, so we will move on to the next step: Addition and Subtraction. You can see there is addition and subtraction in the numerator. is equal to 120, and
is equal to 121. Our problem is now:
Our answer is 1.
