The answer is 3.14 m
The area (A) of the circle with radius r is: A = π · r²
The area of the quarter of the circle is: A1 = 1/4A = 1/4 · π · r²
We have:
A1 = ?
r = ?
π = 3.14
d = 4 m
A diameter d is the twice of the radius r: d = 2r.
Therefore, the radius is the half of the diameter: r = d/2
So, the area of the quarter circle would be:
A1 = 1/4 · π · r² = 1/4 · π · (d/2)² =1/4 · π · d²/2² = 1/4 · π · d²/4 = 1/16 · π · d²
A1 = 1/16 · π · d² = 1/16 · 3.14 · 4² = 1/16 · 3.14 · 16 = 3.14 m
Answer:
David took 16 oranges.
Step-by-step explanation:
We are given the following in the question:
Total number of oranges = 48
Oranges rotten =
Number of oranges rotten =
There were 16 rotten oranges.
Number of good oranges left =
These are equally divided among Ben and David.
Number of oranges each Ben and David get =
Thus, David took 16 oranges.

Step-by-step explanation:
To help you with this topic, I would suggest you revise probability trees.
P(train arriving) = 0.8
P(train arriving on time) = 0.84
P(train arriving late) = 0.86
0.8 x 0.86 = 0.688
Answer: 0.688
