Area = r^2 * 3.14
87.9/3.14 = around 28
Square root of 28 = 5.3
The radius is 5.3
Circumference: diameter * 3.14
5.3 + 5.3 = 10.6
10.6 * 3.14 = 33.3
The circumference is 33.3
500 is 100 times greater than 5 because 5*100=500. :)
We will use the proper formula and solve.
-> A diameter of 48 / 2 = 24 feet as our radius
Area:
A = πr²
A = (3.14)(24)²
A = 1,808.64 ft²
The circle has an area of about 1,808.64 ft²
Circumference:
C = 2πr
C = 2(3.14)(24)
C = 150.72 ft
The circle has a circumference of about 150.72 ft
Answer:
Step-by-step explanation:
The square means a degree angle.
We know that all the angles in a triangle add to degrees. So, we can build an equation for x:
Combining like terms on the left side gives
Subtracting from both sides gives
Dividing both sides by gives
