20 because radius times height will give you the surface area of the shape
Answer:
A. 3.0 m/s
Step-by-step explanation:
Based on the graph,
velocity = Area of the graph
(y : position and x : time)
Let y1 = 2m and y2 = 14m,
t1 = 0s and t2 = 4s
v = (14 - 2)m/(4-0)s
= 12m/4s
= 3.0 m/s
Answer:
A2: 4*4*4 = 64 cm³; 6*6*6 = 216 cm³; etc...
B2: 7*4.5*4 = 126 cm³; 10.5*6*2 = 126 cm³; etc...
Step-by-step explanation:
So in A2 you have cubes, so l=b=h, and only one has to be given, called the "length of side".
In B2 they are different, hence there are 3 rows with l, b and h. But still you multiply them l x b x h
