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
13x−2/3x
=13x+(−2/3x)
Combine Like Terms:
=13x+(−2/3x)
=(13x+(−2/3x)
=37/3x
Answer:
17
Step-by-step explanation:
Opposite sides of the parallelogram AB and CD are the same length, so ...
5x +2 = 8x -7
9 = 3x . . . . . . . . add 7-5x
3 = x
AB = 5x +2 = 5·3 +2
AB = 17 = CD
When plugging this into the calculator, you find:
The answer would be 8.9.
