Hello! here are the basic rules that you need to know to solve these problems:
a diameter is 2 × the radius
the circumference rule is 2×π×radius
I will solve the first question to show how to format.
1: 5/2=2.5
2×2.5×π=5×π=15.7
Answer:
B(1) = 2
Step-by-step explanation:
Function B(x), according to the graph, which point has an x-value of 1? Point (1, 2). So the solution is 2.
The units are always squared.
The area can be found when given the diameter by first finding the radius.
Circumference can be used to find area.
