Answer: 133/2π
Step-by-step explanation:
<u>Area of ends:</u>
Area of Circle = πr²
π3.5²=49/4π
There are two ends so you multiply that by 2 to get 49/2π
<u>Area of Rest:</u>
First, you need to find the circumference using the equation: πd
πx7=7π
Then to find the area you just need to multiply 7π by the height
7π x 6 = 42π
<u>Total surface area</u>
You now just need to add them together
49/2π + 42π = 133/2π

Answer:
12870ways
Step-by-step explanation:
Combination has to do with selection
Total members in a tennis club = 15
number of men = 8
number of women = 7
Number of team consisting of women will be expressed as 15C7
15C7 = 15!/(15-7)!7!
15C7 = 15!/8!7!
15C7 = 15*14*13*12*11*10*9*8!/8!7!
15C7 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2
15C7 = 15*14*13*12*11/56
15C7 = 6,435 ways
Number of team consisting of men will be expressed as 15C8
15C8 = 15!/8!7!
15C8 = 15*14*13*12*11*10*9*8!/8!7!
15C8 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2
15C8 = 6,435 ways
Adding both
Total ways = 6,435 ways + 6,435 ways
Total ways = 12870ways
Hence the required number of ways is 12870ways
