Answer:
12.49 cm
Step-by-step explanation:
One paper is 38.9, so two papers are 77.8 cm.

77.8 - 65.31 = 12.49 cm
Answer:
468.75 = Volume B
Step-by-step explanation:
The volume of two similar figures is related to the scale factor by cube
Volume A
----------------- = scale factor ^3
Volume B
30 2^3
-------------- = ---------
Volume B 5^3
Using cross products
30 * 125 = 8 Volume B
3750 = 8 Volume B
Divide by 8
3750/8 = Volume B
468.75 = Volume B
Answer:1017.36 cm^3
Step-by-step explanation:
Diameter=18cm
Radius=r=18/2=9cm
Height=h=12cm
Volume of cone=1/3 x π x r^2 x h
Volume of cone=1/3 x 3.14 x 9^2 x 12
Volume of cone=1/3 3.14 x 9 x 9 x 12
Volume =(1x3.14x9x9x12) ➗ 3
Volume =3052.08 ➗ 3
Volume =1017.36
Volume of cone=1017.36 cm^3
