Answer:
3, 14, and sqrt205.
2,9, and sqrt85.
Step-by-step explanation:
Check if they fit the Pythagoras theorem c^2 = a^2 + b^2:
3^2 = 9 , 14^2 = 196.
9 + 196 = 205 which is the square of sqrt205.
So this is a right angled triangle.
6^2 + 11^2 = 36 + 121
= 157 Not right-angled.
19^2 + 180^2 = 32761 Not right-angled.
3^2 + 19^2 = 370 Not right-angled.
2^2 + 9^2 = 85, So this is right angled..
Answer:
24
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Divide this by the size of 1 exterior angle to find number of sides, that is
number of sides = 
= 24
Yes! If the raffle tickets are $2 and Amari supposedly purchased 8, that would make the total money for raffle tickets $16. Then if you take the 4 snacks for $1.50 each that would be $6.
16+6=22
The formula for area of a circle is r² x π.
Since we know the diameter, we can firstly divide by 2 to find our radius.
4/2 = 2
Now that we know the radius, we can substitute it in and square the value.
(2)² x π
(4) x π
Since we're finding the area in terms of pi, we won't multiply by pi, giving us the answer of 4π.
Therefore, the area of the circle is equal to 4π.
