What is the volume of a cylinder with base radius 2 and height 9

Step-by-step explanation:

The formula for a cylinder is πr²×h  replace r and h with 2 and 9 getting π·2²·9.

- start calulating also π=3.14 in this situation

3.14×4×9=12.56×9=113.04

when you enter that answer in khan it accepts it as right.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
