\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

What does the formula 4πr² give?

\blue\textsf{\textbf{\underline{\underline{Answer and how to Solve:-}}}}

Formula for Volume of a Sphere:-

\bold{V=\displaystyle\frac{4}{3} \pi r^3}

So the answer is not Option A.

Formula for Surface Area of a Sphere:-

\bold{A=4\pi r^2}

This looks exactly like the formula we need.

So the right answer is

\boxed{\boxed{\underline{\bold{Option\:B}}}}

<h3>Good luck.</h3>

There are 200 balls of the same size inside a dark room. There are 100 white balls, 55 red balls, and 45 black balls. If one stu
Komok [63]

Answer:

Probability of picking Red ball is 27.5%

Step-by-step explanation:

Given:

Total Number of balls = 200

Number of White balls = 100

Number of Red balls = 55

Number of Black balls = 45

We need to find the probability of the ball picked to be red.

Solution:

Now we know that;

Probability is equal to number of Possible Outcomes divide by total number of Outcomes multiplied by 100.

framing in equation form we get;

P(Red) = \frac{\textrm{Number of Red balls}}{\textrm{Total Number of balls}} \times 100

P(Red) = \frac{55}{200}\times100

P(Red) = 27.5\%

Hence Probability of picking Red ball is 27.5%.
