Using Pythagorean theorem, the answer should be 8.7ft
30% of his questions was 6 questions.
Translate that to a math equation where q= total number of questions.
30% x q = 6
.3 x q = 6
q= 6/.3
q= 20
There were 20 questions in the test.
And 30% of 20 is 6 so that is the correct answer.
Hope this helps :)
Is is 60 to 10? that may be it or 6 to 1?
Answer:
sin(5π/6) =
Step-by-step explanation:
The given angle 5π/6 lies at the third quarter
because: (π/2) < (5π/6) < π
The sin at this quarter is +ve
sin(5π/6) = sin ( π - π/6) = sin (π/6) = 1/2
See the attached figure.
Volume of cone = (1/3)pi*r²h
56.52 = (1/3)*3.14*r²*6
56.52/(2*3.14) = r²
9 = r²
r² = 9
r = √9
r = 3
Diameter = 2*r = 2*3 = 6 inches
