Nina [5.8K]

Answer:

2000 workers

Step-by-step explanation:

60%= x

40% = 800 (the ones that arent men)

(800÷2= 400) which means..

40%÷2=400

20%=400 so

40% + 20% = 60%

800 + 400 = 1200

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm. How many cubic cm of popcorn can the cup hold? Use 3.14 as a
katovenus [111]

Answer:

The cup can hold <u>235.5 cubic cm</u> of popcorn.

Step-by-step explanation:

Given:

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.

Use 3.14 as an approximation for pi.

Now, to find cubic cm of popcorn the cup can hold.

Radius ( r ) = 5 cm.

Height ( h ) = 9 cm.

π = 3.14 ( as per question ).

So, to get the cubic cm of popcorn the cup can hold we put formula of volume:

Volume = \pi r^2\frac{h}{3}

Volume=3.14\times 5^2\times \frac{9}{3}

Volume=3.14\times 25\times 3

Volume=235.5\ cubic\ cm.

Therefore, the cup can hold 235.5 cubic cm of popcorn.
