Can Somebody Please Help With This Ive Been Stuck On It For A While class=

Sagot :

Answer:

11.8

Step-by-step explanation:

volume = (1/3) * π * r² * h

1/3*3.14*2.25*5=11.8

Its because the r=radius in which we know that 3 is basicaly the diameter but we need to r the radius so then we do 3/2=1.5 but because its squared we do 1.5*1.5=2.25. So yeah thats the answer

Answer:

F

Step-by-step explanation:

Formula

Volume of cone= ⅓πr²h,

where r is the radius and h is the height

Finding radius

Radius= ½(diameter)

Given that the diameter is 3,

radius

= 3 ÷2

= 1.5 in.

Finding volume

Volume of cone

[tex] = \frac{1}{3} ( \frac{22}{7} )( \frac{3}{2} )^{2} (5)[/tex]

[tex] = \frac{1}{3} ( \frac{22}{7} )( \frac{9}{4} )(5)[/tex]

[tex] = \frac{22}{7} ( \frac{3}{4} )(5)[/tex]

[tex] = \frac{11}{7} ( \frac{3}{2} )(5)[/tex]

[tex] = \frac{165}{14} [/tex]

= 11.786 (5 s.f.)

= 11.8 in³ (3 s.f.)

Note:

You could also enter the values into a calculator to find the volume of the cone and use the exact value of π instead of the estimated value of 22/7.
