Volume of the cylinder=area (circle) x height
area (circle)=πr²
r=radius=4 in.
area=π(4 in)²=16π in²
height=8 in

Volume of the cylinder=(16π in²)(8 in)=128π in³≈402.12 in³

Answer= 128π in³ or 402.12 in³

Create and answer your

shutvik [7]

Step-by-step explanation:

$\frac{20}{48} \times \frac{80}{44}$

Divide the fraction with 4

$\frac{20÷4}{48÷4} \times \frac{80÷4}{44÷4} = \frac{5}{12} \times \frac{20}{11}$

Reduce the number with factor 4

$\frac{5}{12÷4} \times \frac{20÷4}{11} = \frac{5}{3} \times \frac{5}{11}$

Multiply the fractions

$\frac{5 \times 5}{3 \times 11} = \frac{25}{33}$

$\boxed{\green{= \frac{25}{33} = 0.75}}$

The correct scientific notation for the number 500.0 is

marishachu [46]

Answer:

The correct scientific notation for the number 500.0 is $500=5.0\times10^2$

Step-by-step explanation:

While writing a large number in scientific notation we do below mentioned two things.

We take any number between 1 and 10
Then we multiply this number with an exponent of 10.

Hence, any number in scientific notation is in the form $a\times10^b$

Here a is any number between 1 and 10.

b is exponent of 10.

Now, writing 500 in scientific notation, we take a = 5

Hence, we have to take b = 2, since 5 multiplied by 100 equas 500.

Thus, we have

$500=5.0\times10^2$
