Area of a triangle:
A = a * h / 2
where a is the base and h is the height.
For a new triangle:
A ( new ) = 3 a * 3 h / 2 = 9 * a * h / 2 = 9 A
A ( new ) = 9 * 30 = 270 cm²
Answer: The area of resulting triangle is 270 cm² .

How does the volume of an oblique cylinder change if the radius is reduced to 2/9 of its original size and the height is quadrup
Novay_Z [31]
New volume is given by:
New volume=(old volume)×(4×2/9×2/9)
simplifying the above we get:
New volume=(old volume)×16/81
Thus the new volume is 16/81 times the old volume
old volume=πr²h
Hence:
Answer:16/81πr²h
