Answer:
Volume left = 16π cm³ or 50.265 cm³
Step-by-step explanation:
Let's first find the surface area of the tennis ball.
S.A = (4/3)πr³
Radius of a ball = 2 cm
Thus;
S.A = (4/3)π(2)³
S.A = 32π/3
Since there are 3 radius balls that will make the cylinder full, then;
Surface area of 3 balls = 3 × 32π/3 = 32π
Now, formula for volume of cylinder is;
V = πr²h
r = 2 cm
h = 4 × 3 = 12 (since diameter of tennis ball is 4 cm)
Thus;
V = π × 2² × 12
V = 48π
Thus;
Volume left = Volume of cylinder - surface area of 3 balls = 48π - 32π = 16π cm³ or 50.265 cm³
To find the perimeter, you add up all of the sides together.
11 + 7 + 5 + 5
11 + 7 + 10
11 + 17
28 << answer

2.62 is the answer but there’s actually way more numbers than that
Answer: 7, 8
Step-by-step explanation: The way coordinates are written are in X, Y form, with x being horizontal and y being vertical. If you move for units up from 7, 4, then the new coordinates are 7, 8.
That is false the correct answer would be 5
