Find the area of a circle with a diameter

2 answers:

6 0

To get the answer divide the diameter by two, so you can get the radius. So plug it into the formula A=π 8²=π (8²)=64π =200.96 and for multiplying pie I just used 3.14 instead the entire number so I could get it by having the decimal in the hundredths place.

64 pi. Half of 16 is 8 and 8 squared is 64.

For this case we have to define root properties:

$\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a$

In addition, we know that:

$a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}$

On the other hand:

$4 ^ 2 = 16$

Thus, we can rewrite the given expression as:

$\sqrt {4 ^ 2 * a ^ 8 * \frac {1} {b ^ 2}} =\\4 ^ {\frac {2} {2}} * a ^ {\frac {8} {2}} * \frac {1} {b ^ {\frac {2} {2}}} =\\4 * a ^ 4 * \frac {1} {b}$

Karens batting average is 0.444.she was at bat 45 times. how many hits did she get

alexgriva [62]

Answer:

A batting average is simply the ratio of hits/at-bats. So, if Karen were up to bat 1,000 times and she got a hit 444 times, that makes her batting average 444/1,000 = .444.

The good news is you can multiply this ratio by number of at bats to get the number of hits.

So, 45 hits x .444 = your answer.

Hope that helps.
