Answer angle ABC is a complementary angle
1130.9734
volume=πr2h
π x 6 x 10= 1130.9734
You need 6 packages because 5 packages wont be enough pencils for all of the students. You see, 5 times 5 is 25, and we have 27 students. So we buy 6 and have extra.
and also
now, we know that V varies directly to T and inversely to P simultaneously
thus
so
The perimeter , width and length are all one dimensional so the preimeter of the resulting rectangle will be 2.5 * 36 = 90.
The area is 2 dimensional whereas the vase and height are one dimensional so the area will be increased by a factor of 5^2 ( or 25)
New rea = 36*25 = 900
solids are 3 dimensional so the ratio of thereir volumes is 5^3 : 3^3
= 125:27
to answer the last 2 use the formula Volume = pi r^2 h where r = radius and h = height of a cylinder
