Rename 2/5 as a percent_______________________

Mathematics
1 answer:
loris [4]2 years ago
7 0

It can be helpful to remember that "%" is just a shorthand way to write "/100" (divided by 100, or per 100, or per cent). ("Cent" is often used to refer to 100 or 1/100. A "cent" is 1/100 of a dollar, or 1/100 of an acre, for example. A <em>cent</em>ury is 100 years.)

Make the denominator of your fraction be 100. Multiply numerator and denominator by 20/20.

(2/5)×(20/20) = 40/100 = 40%

You can also get there via decimals.

... 2/5 = 0.4 = 0.40 (40 hundredths) = 40/100 (40 hundredths) = 40%

Or, you can multiply by 100%.

... (2/5)×(100%) = (200/5)% = 40%

Find the exact volume of a cone 6yd height 5yd base
Verdich [7]

Answer:

The exact volume of a cone is 10 yd³.

Step-by-step explanation:

Given:

Height of cone (h) is 6 yd and base (b) is 5 yd.

Now, to get the volume we need to find the radius.

So, to find radius we put the formula of base:

Let the radius be r

Base=\pi r^2

b=\pi\times r^{2}

5=\pi\times r^{2}

Dividing both sides by π and using square root on both the sides:

5\div \pi=(\pi \times r^{2}) \div \pi

\frac{5}{\pi}=r^{2}

\frac{5}{\pi}=r^{2}

r^{2}=\frac{5}{\pi}-----1

Now, putting the formula for getting the volume (v) of cone:

Volume = \pi r^2\frac{h}{3}

v=\pi\times r^{2}\times \frac{6}{3}

v=\pi\times r^{2}\times 2

Substituting the value of r^2 from equation (1), we get:

v=\pi\times \frac{5}{\pi}\times 2

v=10 yd³

Volume of cone is 10 yd³

Therefore, the exact volume of a cone is 10 yd³.
