Answer: She is not correct, because she must multiply the base and the height of the triangle and then divide by 2.

Step-by-step explanation:

1. The formula for calculate the area of a triangle is shown below:

$A=\frac{b*h}{2}$

Where $b$ is the base and $h$ is the height.

2. Then, if she applied the method she reasoned, she'd obtain the following area:

$b=\frac{4ft}{2}=2ft\\h=\frac{2.8ft}{2}=1.4ft\\A=2ft*1.4ft\\A=2.8ft^{2}$

3. But actually, Magda should multiply the base and the height of the triangle and then divide by 2. Then, the correct area is:

$A=\frac{4ft*2.8ft}{2}=5.6ft^{2}$

Answer:

$22961.5 cm^{2}$

Step-by-step explanation:

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

30/2 = 15 (to find radius, r)

$V = 3.14 * 15^{2} * 325$

$V = 22961.5 cm^{2}$
