The volume of the spherical piece is 288.55 cm³.
Solution:
Diameter of the sphere = 8.2 cm
Radius of the sphere = 8.2 ÷ 2 = 4.1 cm
The value of π = 3.14
Volume of the sphere ![=\frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D)
![$=\frac{4}{3} \times 3.14 \times(4.1)^{3}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B4%7D%7B3%7D%20%5Ctimes%203.14%20%20%5Ctimes%284.1%29%5E%7B3%7D)
![$=\frac{4}{3} \times 3.14 \times68.921](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B4%7D%7B3%7D%20%5Ctimes%203.14%20%20%5Ctimes68.921)
= 288.55 cm³
The volume of the spherical piece is 288.55 cm³.
Answer:
Independent
Step-by-step explanation:
with replacement the total number of tiles will always remain the same,i.e the sample size will not be changed. so the events are independent.
If there are 12 boys and 13 girls, there are 25 kids in the class total. This means that 13/25 are girls. In order to know the probability, you must divide 13 by 25, which gets an answer of 0.52, which is equal to 52%.
52%
Divide thirty-one by five, and that is the answer
