The correct answer is D. You can see It is the biggest bar and so you can estimate the correct answer.
True! If you have any 3 segments, it could form a triangle, just not a right triangle.
5-(-4)
5 + 4 = 9
exceeds by 9
Answer:
16% or 4/25
Step-by-step explanation:
16 + 5 = 21
25 - 21 = 4
4/25 = 16%
This is right because 21/25 is 84% and 84% + 16% = 100%
Answer:
10 cm.
Step-by-step explanation:
We'll begin by calculating the area of the small bubble. This can be obtained as follow:
Radius (r) = 5 cm
Area (A) =?
Since the bubble is circular in nature, we shall use the formula for area of circle to determine the area of the bubble. This is illustrated below:
A = πr²
A = π × 5²
A = 25π cm²
Next, we shall determine the total area of the small bubbles. This can be obtained as follow:
Area of 1 bubble = 25π cm²
Therefore,
Area of 4 bubbles = 4 × 25π cm²
Area of 4 bubbles = 100π cm²
Finally, we shall determine the radius of the large bubble. This can be obtained as follow:
Area of large bubble = total area of small bubbles = 100π cm²
Radius (r) =?
A = πr²
100π = πr²
100 = r²
Take the square root of both side
r = √100
r = 10 cm
Thus, the radius of the large bubble is 10 cm
