Answer: 157 ft
Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference of a circle which is shown below.
Circumference = 2πr
Notice that the circle has a radius of 25 feet. So we can plug in 25 feet for <em>r</em> in the formula. So we have (2)(π)(25 ft) which is equal to 50π ft.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (50)(3.14) which is equal to 157.
So the circumference of the circle is approximately equal to 157 ft.
Substitute the value of y = 3 into the expression,
7x + 2y = 48
7x + 2(3) = 48
7x = 48 - 6
7x = 42
x = 42/7
x = 6
So, your final answer is 6
Hope this helps!
A line is 180 so you subtract 126 with 180 and get 54. Since a Triangle angles all equal 180 together you add 54 and 43 and subtract 180 and the answer is 83
Percent means per one-hundred
80(24/100)=19.2
