Answer:
7 billion X 1.5%
Step-by-step explanation:
Im pretty sure this is not it, but at least i tried. And how is this high school material lol
The formula for area of a circle is:
A=(pi)r^2
If diameter is 5.5, divide by 2 to find radius is 2.75. 2.75^2 is 7.5625 then multiplied by 3.14 (pi) is 23.746.
Depending on how you round, about 23.7 square feet were painted.
A straight angle is equal to 180 degrees. 180-80=100. 100-60=40. so y=40. vertical angles are congruent so x=40 degrees.
If you download Photomath and scan your question it will give u the answer;)
