It’s A. 38! You divide the diameter in half and use the radius to find the area of the circle
Answer:
I think the answer is 1
Step-by-step explanation:
-49÷7=-7
-7÷-7=1
After 1.4 seconds, t = 1.4.
h(t) = 150 - 9(1.4)
Multiply 9 by 1.4 to get 12.6.
h(t) = 150 - 12.6
Subtract 12.6 from 150 to get 137.4.
h(t) = 137.4.
The height of the ball would be 137.4 after 1.4 seconds.
Hope this helps!
