Answer: 4 units
Step-by-step explanation:
Given : AB is the diameter of a circle.
Then, the central angle for arcADB must be because the central angle subtended by diameter is .
The length of arc is given by :-
Hence, the length of the radius of the circle = 4 units

Answer:
Length = 8 in. Perimeter = 28 in.
Step-by-step explanation:
The equation for finding area is: A = l*w
Let's put the values we already know into the equation
48 = l * (6)
Divide both sides by 6 to isolate the l
8 in. = l
We know this answer is correct because 8 * 6 = 48
Now that we know that the length is equal to 8, we can solve for the perimeter.
To find the perimeter you have to add the values of all of the sides together.
Since we know that the top of a letter box is in the shape of a rectangle, we know that two of the sides are 6 in. and the other two sides are 8 in.
6 + 6 + 8 + 8 = 28 in.
Answer:
Proof given by contradiction.
Step-by-step explanation:
Given that:
To prove:
is prime if and only if no positive integer > 1 and divides .
Solution:
First of all, let is a composite number i.e. not a prime number such that:
and and are prime and divides and also divides .
Let
or
1. :
is prime and is a divisor of .
2. :
We have assumed that
is a prime number and is a divisor of .
But we are given that no prime number divides but we have proved that divides .
So, it is a contradiction to our assumption.
Therefore, our assumption is wrong that is a composite number.
Hence, proved that is a prime number.
