Answer: ![282.85\ cm^2](https://tex.z-dn.net/?f=282.85%5C%20cm%5E2)
Step-by-step explanation:
Given
Radius of cylinder ![r=5\ cm](https://tex.z-dn.net/?f=r%3D5%5C%20cm)
The height of the cylinder is ![h=9\ cm](https://tex.z-dn.net/?f=h%3D9%5C%20cm)
The surface area of a cylinder is ![2\pi rh](https://tex.z-dn.net/?f=2%5Cpi%20rh)
If only the outer is considered then, the area required is
![\Rightarrow A=2\times \dfrac{22}{7}\times 5\times 9\\\\\Rightarrow A=282.85\ cm^2](https://tex.z-dn.net/?f=%5CRightarrow%20A%3D2%5Ctimes%20%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%205%5Ctimes%209%5C%5C%5C%5C%5CRightarrow%20A%3D282.85%5C%20cm%5E2)
Answer:
Subtract 58 from both sides
Step-by-step explanation:
93 = x + 58
Subtract 58 from both sides
93- 58 = x+58-58
35 = x
Answer:
Step-by-step explanation:
<u>Total number of outcomes:</u>
<u>Number of combinations of getting 6 heads:</u>
- 15C6 = 15!/6!(15-6)! = 5005
<u>Required probability is:</u>
- P(6 heads out of 15 flips) = 5005/32768 = 0.1527... ≈ 15.3%
Correct choice is D
