Answer:
correct option if Option D
1288.45 = 1288.45 · 100% = 128,845
...
Using the Pythagorean theorem, a² + b² = c², we can solve for 'c'.
We know the length of sides 'a' and 'b', and this is all we really need to know. The angle value of angle 'c' is irrelevant to finding the length of side 'c' (which I'm assuming is the hypotenuse).
18² + 24² = c².
324 + 576 = c².
900 = c². Now find the square root of 900 to get the value of 'c'.
30 = c. <= And there is your answer.
Answer:
B) 3.14(144)
D) 2(3.14)(12)
E) 3.14(24)
Step-by-step explanation:
The formula to find the area of a circle is
, where r = radius, while the formula to find the circumference of a circle is
or
, where r = radius and d = diameter.
Given the information above, option B) is a correct statement because 12^2 equals 144, and once you're done solving the square, you multiply it by 3.14. Next, option D) and E) are correct, too, because they exactly follow
and
. Furthermore, for E), diameter = twice the radius, so it makes sense to multiply 3.14 by 24.
