Answer:
Option (B).
Step-by-step explanation:
Option (A).
A, F and B are lying on a line on the plane M.
True.
Option (B).
CD lies on the plane M, but its not clear that angle between the plane M and P is 90°.
False.
Option (C).
A, B and C are coplanar.
Since, these three points lie on the plane M, they are coplanar.
True.
Option (D).
Plane M intersects plane P in FH.
Since, line of intersection of the two planes M and P will be FH.
True.
Therefore, Option (B) will be the correct option.
Still begging? OK. Let's do it with algebra first then put in the numbers.
We're given the Circumference of a circle C, and we want the area A.
The radius is related to the circumference by
C = 2π r
The area is related to the radius by
A = π r²
Solving for r in the first equation,
r = C/(2π)
So the area is
A = π ( C/(2π) )² = πC²/(4π²) = C²/(4π)
---------------------------
OK we're given C=25 1/7 inches, π≈22/7
C = (7×25 + 1)/7 = 176/7 = (22×8)/7
That's a little convenient.
A = C²/4π = ( (22×8)/7 )² / (4 (22/7) ) = (8²/4) (22/7) = (16*22)/7 = 352/7
After those nice numbers they want an approximation. How disappointing.
A = 50.2857142857 sq inches
Answer: 50.29
Answer:
125 students ride their bike to school
Step-by-step explanation:
We can set a proportion.
5 / 32 = x / 800
where x is the number of students out of 100 who ride their bikes.
Cross multiply.
32x = 4000
Divide both sides of the equation by 32.
x = 125
125 students out of 800 students ride their bikes to school.
