So the amount needed=area of circle times height
area formula=pi times radius^2
height=3/4
so
pi=aprox 3.14
radius=7
3.14 times 7^2
3.14 times 49
153.86
times 3/4
115.395 in^3
answer is 115.4 cubic inches
60% of 40 is 24 and 40-24= 16 so she got 16 wrong
Take the number "of" divided by the other number then multiply it by 100% to get the percentage.
(21/33.5) ×100%= 62%
Combine like terms.
6A*7A = 42A
3B*7B = 21B
Now we have our most simple expression:-
21B*42A
Answer:
A obtuse
Step-by-step explanation:
The sum of the given angles is 86°, so the third angle is 180° -86° = 94°. Its measure is more than 90°, so it is an obtuse angle. When a triangle contains an obtuse angle, it is classified as an obtuse triangle.
