The diagram shows a pyramid whose base is a regular pentagon of area 42 cm2 and whose height is 7 cm.

1 answer:

8 0

We know, Volume = Area of base pentagon * h/2
V = 42 * 7/2
V = 21 * 7
V = 147 cm³

In short, Your Answer would be 147 cm³ [ Option D ]

Hope this helps!

Plz help me with all of this question here and explain how was the incorrect answer obtained

larisa [96]

Answer:

1.) 9

2.) 20

Step-by-step explanation:

1.) 39 is incorrect because they didn't follow the PEMDAS rule.

They subtracted 2 from 15 which is 13, and then they multiplied 13 by 3.

The correct way is to multiply 2 times 3 which is 6, and then subtract 6 from 15 which is 9.

2.) 12 is incorrect because they didn't use PEMDAS.

They added 8 to 16 which is 24, and then divided 24 by 2.

The correct way is to divide 8 by 2 which is 4, and then add for to 16 which 20.
