For big circle the diameter is 10 so the radius is 5. Use the equation for the area of a circle pi r^2.
Pi is 3.14 as said in the question.
So 3.14 x 5^2 or 25 x 3.14=78.5
For smaller circle, diameter is 6cm so the radius is 3.
Using the same area of a circle equation it would equal 3.14 x 3^2 or 9 x 3.14=28.26
Take 28.26 away from 78.5 to get 50.24.
To the nearest tenth would mean it would equal 50.2
The last option is the answer

n= -9
Step-by-step explanation:
The calculator is correct haha, You're welcome.
Let the number of baskets be x
Let the number of points be y
32 +3x = y
19 + 4x = y
Rearrange both equations then solve them as simultaneous equations
32 = y - 3x
19 = y - 4x
y - 3x = 32
- y - 4x = 19
x = 13
Substitute x into one of the equations
y - 3x = 32
y - (3 x 13) = 32
y - 39 = 32
y = 32 + 39
y = 71
Number of baskets (x) = 13
Number of points (y) = 71
Answer:
22 is the avrage rate of elavation change in feet per second if a sumbarine dives 440 feet in 20 seconds
