To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.
we have:
=> 6 ÷ 11 = 12 ÷ AB
=> AB = 12 × 6 ÷ 11 = 72/11 ≈ 6,5
Answer: 72/11 ≈ 6,5
P/s: CA = CD + AD = 6 + 5 = 11
Ok done. Thank to me :>
Sometimes should be the answer
Answer:
n=601
Step-by-step explanation:
Formula used:
Solution:
Where,
As there is no previous estimate for p
Then, p=0.5
Here on using the table
Also,
E=0.04
p=0.5
Thus,
n=600.2279407
On approximating the value,
n=601
