Well A should be congruent to S because (Base Angles Therom)
A =S
Answer:
128.86 cm^2
Step-by-step explanation:
So to start off we need to find the area of the rectangle.
The formula for the area of a rectangle is
×
.
L stands for the length which is 12 and w is the width which is 11.
So 11 × 12 = 132 cm^2.
Now time for the area of a circle.
The formula for that is
.
So first we need to do 1 × 1 which is 1.
Then 1 ×
which is just
.
Then we do 132 -
which is an irrational number.
It looks like this shortened 128.858407346.
Now rounding to the nearest hundreth it would be 128.86 cm^2.
Hence, the area of the shaded region is 128.86 cm^2.
To change a decimal into a percent,
move the decimal point 2 places that way ==> .
Examples:
0.25 = 25 %
0.8439 = 84.39 %
A.) 38.92 the sales tax is $2.97 so 35.95 + 2.97 = 38.92
5280/25, ignoring the remainder, equals 211. That's the answer
