Answer: The radius of the ball is 7 meters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a sphere: 4 π r^2
Replacing with the value given:
615.75 = 4 π r^2
Solving for r (radius):
615.75 /4π= r^2
√(615.75 /4π) =r
r = 6.99 = 7m (rounded)
The radius of the ball is 7 meters.

Originally:
Total liquid volume = 1 L
Sugar volume = 10% of 1L = 0.1 L
Finally:
Sugar volume = (1/4) of 0.1 L = 0.025 L
Total liquid volume = 1 L
Percentage of sugar = 100*0.025 = 2.5%
Answer: 2.5%
Answer is B: 81.
Step by step:
8% of 75 is 6
And:
75+6= 81
Which mean the answer is “B”
Row 11 of pascals triangle is as follows;
1 11 55 165 330 462 462 330 165 55 11 1
Therefore, the fourth is 165
The ninth is also 165
Hope this helps :)
