Answer:
The answer is
<h2>134 ft³</h2>
Step-by-step explanation:
Volume of a hemisphere is given by
where
r is the radius of the hemisphere
From the question
diameter = 8 ft
radius = 8/2 = 4 ft
Substitute the value into the above formula and solve
We have the final answer as
<h3>134.0 ft³ to the nearest tenth</h3>
Hope this helps you
3 15/ 5 16 doesn’t need to be simplified
Answer:
(a). (i) ; (ii) ; (iii); (iv)
(b).
Step-by-step explanation:
The formula you need to use is:
Then, in this case:
(a) Susbtituting values, we get:
(i)
(ii)
(iii)
(iv)
(b) Observe that as the time after 2 second gets smaller, the average velocity gets closer to . Therefpre, we can can estimate that the instantaneous velocity when is:
I believe that b.Fractions are rational numbers is not true
sorry if its wrong
