Answer:
Yes
Step-by-step explanation:
If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle
longest side = 7.5
7.5² = 56.25
2.1² + 7.2² = 4.41 + 51.84 = 56.25
Thus the 3 values form a right triangle.
Answer:
They are 30.93 in³ altogether.
Step-by-step explanation: V = 4/3 π r³
r = 2.7/2 = 1.35
π x 1.35 x 1.35 x 4/3 = 10.31 in³
10.31 x 3 = 30.93

Answer:
A. 1/4 as large
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
Cut the radius in 1/2
V = pi (1/2r)^2 h
V = pi (1/4) r^2 h
V = 1/4 pi r^2 h
The volume is 1/4 what is was before we cut the radius in 1/2
