Answer:r=20 cubic inches
Step-by-step explanation: Looking at this question critically and solving it mathematically, then we are going to say the volume of cylinder is πr^2h
V=15072 cubic inches r=? H=12cubic inches
15072cubic inches=3.14×r^2×12cubic inches
15072cubic inches=37.68 cubic incher^2
r^=400
We are going to take square of both sides, and our answer will now be
r=20 cubic inches
Answer:
79.4 m
Step-by-step explanation:
In this problem we deal with a right triangle with hypotenuse 90 m. We are told that tan Ф = 15/8; 15 represents the vertical distance of the kite off the ground and 8 represents the horizontal distance from the kite flyer to the kite. This is sufficient info from which to determine the angle of elevation from kite flyer to kite: tan Ф = 15/8 yields Ф = 1.08 radians.
Using this same angle Ф = 1.08 radians, sin Ф = (vertical distance) / hypotenuse = sin 1.08 rad = 0.882.
Then the vertical distance (height of the kite) is
(90 m)(0.882) = 79.4 m

Answer:
The greatest common factor is 20
Step-by-step explanation:
Rewrite 40 as 20*2
Rewrite 60 as 20*3
=20*3m-20*2
Factor out common term 20;
20(3m-2)
Answer:
The number is - 9.
Step-by-step explanation:
(y ÷ 9) - 1 = - 2
(y ÷ 9) - 1 + 1 = - 2 + 1
y ÷ 9 = - 1
y ÷ 9 × 9 = - 1 × 9
y = - 9
