Whats The Volume Of The Figure Below class=

Sagot :

12651241idn

Answer:

41.89 cm3

Step-by-step explanation:

Given : Height = 10 cm

Given: Radius = 2 cm

Find the volume,

The formula for volume is,

V = π([tex]r^2[/tex])[tex]\frac{h}{3}[/tex]

Fill in the formula with the given values,

π · [tex]2^2[/tex] · [tex]\frac{10}{3}[/tex]

= 41.8879.....

Round answer to the nearest hundredth,

(The Rule For Rounding: the last digit is less than 5, keep the previous digit the same. If it's 5 or more then you should round the previous digit up.)

41.8879

7 is more than 5 so bring the 8 up to a 9,

41.89

Therefore the answer is 41.89 cm3.

Answer:

41.9 cm³ (nearest tenth)

Step-by-step explanation:

[tex]\textsf{Volume of a cone}=\sf \dfrac{1}{3} \pi r^2h \quad\textsf{(where r is the radius and h is the height)}[/tex]

Given:

  • r = 2 cm
  • h = 10 cm

[tex]\begin{aligned}\implies \textsf{Volume} &=\sf \dfrac{1}{3} \pi \cdot 2^2 \cdot 10\\\\ & = \sf \dfrac{1}{3}\pi \cdot 40\\\\& = \sf \dfrac{40}{3}\pi\\\\ & = \sf 41.88790205\:cm^3\end{aligned}[/tex]

Therefore, the volume is 41.9 cm³ (nearest tenth)
