The diameter of the base of the cone measures 8 units.

kati45 [8]

Answer: $32\pi$ cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

$V_{cone}=\frac{1}{3}\pi r^2h$

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

$r=\frac{8units}{2}\\\\r=4units$

Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:

$V_{cone}=\frac{1}{3}\pi (4units)^2(6units)$

$V_{cone}=32\pi \ units^3$

There was 4.35% error in Diego's measurements.

Step-by-step explanation:

Given,

Length measured by Diego = Approx value = 22 cm

Actual length = Exact value = 23 cm

Percent error = $\frac{|approx-exact|}{exact}*100$

$Percent\ error = \frac{|22-23|}{23}*100\\\\Percent\ error = \frac{|-1|}{23}*100\\\\Percent\ error = \frac{1}{23}*100\\\\Percent\ error = \frac{100}{23}\\\\Percent\ error = 4.347\%$

Rounding off to nearest hundredth

Percent error = 4.35%

There was 4.35% error in Diego's measurements.
