Answer:

Step-by-step explanation:

Total count= 14 + 21 + 16

= 51

Mean value = Total count / number of values

= 51/3

= 17

Hence, Total count - mean value = 51 - 17

= 34

What is the volume of a cone with a diameter of 30 feet and a height of 60 feet use 3.14 for pie

Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: $\frac{1}{3} *b*h$

$\frac{1}{3} *$ π $*r$ ² $*h$ =

$\frac{1}{3} *3.14*15^{2} *60=\\$

$\frac{1}{3} *3.14*225*60=$

$\frac{1}{3} *3.14*13,500=\\$

$\frac{13,500}{3} *3.14=\\$

$4500*3.14=$

14,130 feet³

Find the

Mazyrski [523]

Answer:

54 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the side length ) then

$\frac{s^2\sqrt{3} }{4}$ = 81 $\sqrt{3}$ ( multiply both sides by 4 to clear the fraction )

s² $\sqrt{3}$ = 324 $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

s² = 324 ( take the square root of both sides )

s = $\sqrt{324}$ = 18

Thus

perimeter = 3 × 18 = 54 cm
