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.

Gnom [1K]

\\ \sf\longmapsto \dfrac{d}{dx}2xe^x

  • Apply product rule

\\ \sf\longmapsto \dfrac{d}{dx}2x(e^x)

\\ \sf\longmapsto 2x\dfrac{d}{dx}e^x+e^x\dfrac{d}{dx}2x

\\ \sf\longmapsto 2xe^x+2e^x

\\ \sf\longmapsto 2e^x(x+1)

Log(5x-4)-log(×+1)=log4​
Anna007 [38]

Answer:

x = 8

Step-by-step explanation:

log(5x-4)-log(x+1)=log 4

log [ (5x - 4) / (x+ 1) ] = log 4

[ log (a/b) = loga - logb]

(5x - 4 ) / ( x + 1) = 4

(5x - 4) = 4x + 4

5x - 4x = 4 + 4

x = 8

Hope it will help :)❤
