What goes in the empty box is 22 because they notes get multiplied by 2 to equal the time
<h3>Calculate the area of the circle</h3>
To start solving this exercise, we obtain as data:
To find the area of the circle. We apply the following formula: A =π r², where
We substitute our data in the formula and solve:
Substituting values into the equation:
Taking the square root:
Multiplying
Therefore, the area of the circle is 300 ft².
Answer:
Step-by-step explanation:
Answer:
∡J and ∡K are complementary
Step-by-step explanation:
since ∡L is a right angle, that means it measures 90 degrees
since there are a total of 180 degrees inside a triangle, angles J and K must add up to 90 which means they are complementary
Answer: The perimeter is going to increase 25% from the square to the pentagon.
Step-by-step explanation:
- A square is a quadrilateral having its all sides equal.
- A equilateral triangle is a triangle that has equal sides.
Let the side of the given square be x.
Perimeter of square =4x
If a square is changed into a pentagon by building an equilateral triangle on top of it , Then the base of equilateral triangle will occupy the same side-length as that of square.
Thus , the pentagon will become a regular pentagon having all its sides equal.
Perimeter of pentagon = 5(side)= 5x
Increase in perimeter = Perimeter of pentagon- Perimeter of square
= 5x-4x= x
Now , the percent increase in perimeter =
Hence, the perimeter is going to increase 25% from the square to the pentagon.
