Step-by-step explanation:
we first find area of the whole shape outer core which is
we use the fomulae of a circle 22/7 represent pie
=1/2 *22/7*8,5
=13,36
then we find the inner core of the shape which is
1/2*22/7*5,5
=8,64
then we substracte to get the shaded part 13,36-8,64
=4,72cm
Answer:
The height of the third bounce is 10.8 feet
Step-by-step explanation:
Let us solve the question
∵ A ball is dropped from a height of 50 feet
∵ The function f(x) = 50 gives the height in feet of each bounce
∵ x is the bounce number
∵ We need to find the height of the third bounce
∴ x = 3
→ Substitute x by 3 in the function above
∵ f(3) = 50(0.6)³
∴ f(3) = 50(0.126)
∴ f(3) = 10.8
∴ The height of the third bounce is 10.8 feet
15 and 45 becuase bith 3 and 8 can go into them.
