V = $\pi \pi$ $r^{2}$ h

1. Find the radius.

8/2 = 4

2. Square the radius.

$4^{2}$ = 16

3. Multiply that by pi.

3.14 * 16 = 50.24

4. Multiply that by the height.

50.24 * 20 = 1004.8

5. Now find 60% of that.

1004.8 * 0.6 = 602.88

V = 602.88 $m^{3}$

Honestly, it's been a while since I've done this, but I believe this is the answer.

Answer:

f(x) = f(-x) = x^2 -1 is an <u>even</u> function

Step-by-step explanation:

When f(x) = f(-x), the function is symmetrical about the y-axis. That is the definition of an <em>even</em> function.

Electricity City increases the price of televisions by 25%. If a television now sells for

Burka [1]

Answer:

340

Step-by-step explanation:

As it was increased by 25%, $425 is 125% of the original price, so we can get back to 100% by dividing 425 by 5 [85], so 85 is 25% of the price. We can now get the original price by subtracting 85 from 425 (or you could multiply 85 by 4) which is 340

You can check this answer by multiplying 340 by 1.25

If the answer is 425, then it is correct, else, not. [it is]
