28.3
Step-by-step explanation:
imagine it's a complete circle, and find its are
pi × r^2
which is 36pi (keep ur answer in pi for now)
because it's a quarter of a circle ( 1/4) we decide the are of the full circle by 4 to get the quarter's area
36pi ÷4 = 28.27433388 which is about 28.3 ( as u see we kept it in pi for a more accurate number)
Answer: 3 and 12
<u>Step-by-step explanation:</u>
Let x represent one of the numbers and y represent the other number. Then,
Sum: x + y = 15 → y = 15 - x
Product: xy = 36
Use substitution method by replacing "y" with "15 - x" in the second equation, then solve for x:
x(15 - x) = 36
15x - x² = 36
0 = x² - 15x + 36
0 = (x - 3)(x - 12)
0 = x - 3 and 0 = x - 12
x = 3 x = 12
Answer:
<h2>
43°</h2>
Step-by-step explanation:
The sum of measures of angles in triangle is 180°, so the measure of the ohter acute angle:
180° - 90° - 47° = 43°

Answer:
0
Step-by-step explanation:
Substitute the given values for a and b into the expression
(18 + 14) - (18 - 14)²
= × 32 - 4²
= 16 - 16
= 0
