What is 2/3(3x+9)=−2(2x+6)

What is the volume of a sphere that has a diameter of 18 in.?

True [87]

The formula is 4/3 times pi times radius cubed. The radius is 9. 4/3 is 1.33. 3.14 times 9 cubed is 81 times 3.14. That is 254.34. 1.33 times 254.34 is 338.2722. That rounds to 338.

Step-by-step explanation:

The question is incomplete as the attachment of the prism is not given.

From the attachment:

$L =10cm$ -- Length

$W = 4cm$ -- Width

$H=5cm$ -- Height

Required

Determine the volume

So, the volume is:

$Volume = Length * Width (* Height$
