H=80 ft
Distance from horizon
=sqrt(h/0.57) miles
=sqrt(80/0.57) miles
=11.85 miles.
Answer:
0
Step-by-step explanation:
h(t) = (t + 3)² + 5, -5 ≤ t ≤ -1
The average rate of change is the change in h over the change in t.
(h(-1) − h(-5)) / (-1 − (-5))
= ((-1 + 3)² + 5 − ((-5 + 3)² + 5)) / (-1 + 5)
= (4 + 5 − 4 − 5)) / 4
= 0
Answer:
r= 13ft
Step-by-step explanation:
You are looking for the radius
The Area of a circle is
πr2=530.66
(3.14)r2=530.66
Divide both sides by 3.14
r2=169
Square root both sides to get radius
r=13 feet
Answer:
678.24cm³
Step-by-step explanation:
Volume of cylinder = # r² h
Where # = 3.14
r = radius = d/2 = 12/2 = 6cm
h = 6cm
Therefore
Volume = #r²h
= 3.14 × 6² × 6
= 3.14 × 36 × 6
= 678.24cm³
