2(2)+2(6)= 16, so the perimeter must be 16. Let’s make one of the side lengths l = 3, so 2(3)+2(w)= 16, or w = 5. You can check by multiplying the dimensions that the areas are different.
Y = 68°
Corresponding angles between parallel lines are equal
x and y form a linear pair.
x + y = 180°
68 + x= 180
x= 112°
Answer:
why not. I JUST GOT 41 POINTSSSSS
Step-by-step explanation:
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.
