72k² = 9 x 8 x k x k = 3² x 2² x 2 x k x k

so √72k² = √(3² x 2² x 2 x k x k) = √3² x √2² x √2 x √k² = 6k√2

What is the surface area of a 24ft by 16 ft cylinder 288ft2 , 384ft2 , 19ft2 , 672ft2
Viefleur [7K]

The surface area of the cylinder will be 1206.37 square feet.

<h3>What is surface area?</h3>

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called as the surface area.

Given that the radius of the cylinder is r = 12 ft and the length of the cylinder is 16 ft.

The volume of the cylinder is calculated as:-

V = 2πrl

V = 2 x π x 12 x 16

V = 1206.37 square feet.

Therefore the surface area of the cylinder will be 1206.37 square feet.

To know more about a surface area follow

A bee flies at 9 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 13 ​minutes, and then
Kobotan [32]

Complete Question

A bee flies at 9 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 13 ​minutes, and then flies directly back to the hive at 6 feet per second. It is away from the hive for a total of 16 minutes. What equation can you use to find the distance of the flowerbed from the hive?

Answer:

The equation is 960  = \frac{Z}{9}+ \frac{Z}{6} + 780

Step-by-step explanation:

From the question we are told that

The velocity of the bee is v =  9ft/s =

The duration on the flowerbed is t =  13 \  minutes  =  780 \  s

The velocity back to his hive is u = 6ft / s

The total time away from it hive is t_t  =  16 \  minutes  =  960  \ s

Now let assume the distance of the flower bed from the hive is Z

Generally the time taken for the bee to travel to the flower bed from its hive is

t_1 =  \frac{Z}{9}

The time taken for the bee to fly back to his hive is

t_2 =  \frac{Z}{6}

Generally the total time the bee spent outside of his house is mathematically represented as

t_t  =  t_1 + t_2 +  t

=> 960  = \frac{Z}{9}+ \frac{Z}{6} + 780
