Answer:

18 $\pi$

Step-by-step explanation:

area of the "left most" side disk would be $\pi r^{2}$ = 9 $\pi$

the height of the disk is = 2

thus the area would be 18 $\pi$ units cubed

Answer:

56.55 units

Step-by-step explanation:

If we rotates this rectangle we will get a cylinder.

The base of this cylinder is a circle with a radius of 3 units (the high of the rectangle).

And the high of this cylinder is 2 units.

Volume of cylinder is given by the formula :

V= h.pi.r²

so V= 2×3.14×9

= 56.55 units

Mashutka [201]

Answer:

Z - score = 2.83

Step-by-step explanation:

Given the following :

Number of samples (N) = 60

Sample mean (x) = 41.9mg

Population mean (μ) = 40mg

Population standard deviation (sd) = 5.2

Using the relation :

Z = (x - μ) / (sd / √N)

Z = (41.9 - 40) / (5.2 / √60)

Z = 1.9 / (5.2 / 7.7459666)

Z = 1.9 / 0.6713171

Z = 2.8302570

Therefore, the z-score = 2.83

What is the height of cylinder with a surface area of 226.08 square meters and a radius of 3 meters? (Use 3.14 for π.) 27 meters

zalisa [80]

We know that
surface area of cylinder=2*[area of the base]+perimeter of base*height

area of the base=pi*r²
r=3 m
area of the base=pi*3²----> 28.26 m²

perimeter of the base=2*pi*r
r=3 m

perimeter of the base=2*pi*3----> 18.84 m

surface area=226.08 m²
226.08=2*[28.26]+18.84*h----> 18.84*h=226.08-2*28.26
18.84*h=169.56-------> h=169.56/18.84-----> h=9 m

the answer is
9 m
