now,

Area of an equilateral triangle :

=》

$\dfrac{ \sqrt{3} }{4} {a}^{2}$

where,

a = 8 ( side measure )

=》

$\dfrac{ \sqrt{3} }{4} \times 8 \times 8$

=》

$\sqrt{3} \times 16$

=》

A cylinder has a base diameter of 8ft and a height of 20ft. What is its volume in cubic ft, to the nearest tenths place?

jenyasd209 [6]

Answer:

$4022.9$

Step-by-step explanation:

Volume of a cylinder is given by cross sectional area multiplied by height hence

V=Ah

Since the cross sectional area of

$A=\pi r^{2}$

Substituting the formula for A into formula for volume then

$V=Ah=\pi r^{2}h$

Substituting 8ft for r and 20 ft for h then

$V=Ah=\pi 8^{2}\times 20=4022.8571428571\ ft^{3}\approx 4022.9\ ft^{3}$

Rounded off to the nearest tenths, the volume is equivalent to

$4022.9$
