Area of a sector of a circle is (Angle of Sector/360°)*πr^2
If you plug in the given values, you get (30°/360°)*36π
Simplify the equation.
(1/12)*36π
Simplify the equation again and you get your answer.
Area = 3π
Answer:
SAS
Step-by-step explanation:
We have AM = MH
Then Angle AMT equal to angle HMT
Then side MT equal to MT
The triangles are congruent by side angle side
Answer:
20.54%
Step-by-step explanation:
the first thing to know the percentage change, is to notice if the average increased or decreased, if it was initially 73 and then 88, we can say that increase, therefore the change is positive, now to calculate the exact change we must calculate the quotient of these numbers:
88/73 = 1.2054
which means that 0.2054 is the proportion of increase, to pass it to a percentage we must multiply by 100, that is:
0.2054 * 100 = 20.54%
which means that the percentage change was 20.54%
13 3/4 + x = 7 1/4
becomes x = 13 3/4 / 7 1/4
13 3/4 = 55/4
7 1/4 = 29/4
55/4 / 29/4 = 55/4 * 4/29 = 220/116
220/116 reduces to 1 26/29
