sashaice [31]

Answer: $2.09ft^3$

Step-by-step explanation:

$Formula: V=\pi r^2 \frac{h}{3}$

Plug in your values.

$V=(3.14)(1ft)^2(\frac{2ft}{3})$

Square 1ft.

$V=(3.14)(1ft^2)(\frac{2ft}{3})$

Plug this into a calculator or do it manually.

$V=2.09ft^3$

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w

netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

$\frac{1}{2} \times 100 = 50$

Add both skateboarding and walking

$30\% + 50\%\\\\= 30 + 50\\\\= 80$

Now, subtract that from a whole percent

$100 - 80 = 20\\\\20\%$

Convert it to a decimal

$20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2$

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
