Answer:
radius = 5 units
area of a circle = 15.7units²
Step-by-step explanation:
given that the circumference of a circle = 31.4
radius = ?
recall that the formulae for finding the circumference of a circle = 2πr
circumference of a circle = 2 x 3.14 x r
31. 4 = 6.28r
divide both sides by the coefficient of r which is 6.28
31.4/6.28 = 6.28r/6.28
5 = r
radius = 5 units
therefore the radius of the circle whose circumference is 31.4 units is evaluated to be 5units
to find the area of the circle
recall the formula = πr²
area of a circle = 3.14 x 5²
area of a circle = 3.14 x 25
area of a circle = 15.7units²
M<2 = 60
m<1 = 180 - 60
m<1 = 120
answer
<span>B. 120</span>
175 - 10 = 165 ÷ 5 = 33

This is an example of a Circle Graph, a circle graph is like a Pie chart, and In graph theory, a circle graph is the intersection graph of a set of
chords of a circle. That is, it is an undirected graph whose vertices
can be associated with chords of a circle such that two vertices are
adjacent if and only if the corresponding chords cross each other.
Look at the graph I showed you
