Answer:
area = 147.03 cm²
Step-by-step explanation:
area =16.9 x 8.7 = 147.03 cm²
1/2 because 25 ÷ 25 = 1 and 50 ÷ 25 = 2
Answer:
89/100
Step-by-step explanation:
Answer:
12.83 inch^2
Step-by-step explanation:
To calculate the area of each piece, we need to first need to calculate the area of the pizza as a whole.
Mathematically the area A of the pizza can be calculated using the formula;
A = π * r^2
where our r here is 7 in
Thus, A = 22/7 * 7 * 7 = 154 inch^2
The area of each piece of the pizza is thus 154/12 = 12.8333333 inch^2
To the nearest hundredth, this is 12.83 inch^2
Check the picture below.
now, let's take a peek at that above, DQ = UA and QU = AD, so opposite sides of the polygon are equal.
Now, let's check the slopes of DQ and QU
keeping in mind that perpendicular lines have negative reciprocal slopes, let's notice that the reciprocal of 1/1 is just 1/1 and the negative of that is just -1/1 or -1, so QU has a slope that is really just the negative reciprocal of DQ, those two lines are perpendicular, thus making a 90° angle, and their congruent opposite sides will also make a 90°, that makes QUAD hmmm yeap, you guessed it.
