0.8 is 20% of what number?

1 answer:

6 0

0.8 is 20% of 4. This is because 20% of something occurs when something is divided by 5, since it is 1/5 of 100. You multiply 0.8*5, and you get 4.

Step-by-step explanation:

As they said, I will be using 3 as pi.

$3$ (pi) $* (\frac{26}{2})^2$ (radius squared)

Without annotations: $3*\frac{26}{2}^2$

$3*\frac{26}{2}^2$

$3*13^2$ ; $13*13=169$

$3*169$

$507$
