An empty swimming pool needs to be filled to the top. The pool is shaped like a cylinder with a diameter of 6m and a depth of 1.

adelina 88 [10]

Follow this as an example

An empty swimming pool needs to be filled to the top. The pool is shaped like a cylinder with a diameter of

10 m

and a depth of

1.4 m

. Suppose water is pumped into the pool at a rate of

11 m3

per hour. How many hours will it take to fill the empty pool?

Use the value

3.14

for

, and round your answer to the nearest hour. Do not round any intermediate computations.

The formula for the volume of a cylinder is ∏r2h. The problem gives d=10m, so r=5m.

The pool holds (3.14)*52*1.4 m3 = 109.9 m3 of water.

At a rate of 11 m3 per hour:

( 109.9 m3 ) / (11 m3/hr) = 9.990909 hr.

rounding to the nearest hour, this is 10 hours

In a 30cm by 25cm rectangle, a quadrant of a circle of radius 7cm has been cut away from each corner. What is the perimeter of t

lidiya [134]

Answer:

Perimeter = 98 cm

Area = 596 $cm^{2}$

Step-by-step explanation:

Please refer to the attached image for the resultant figure when a quadrant of circle with radius 7 cm is cut from a rectangle of sides 30 cm and 25 cm.

Perimeter of a figure = Sum of all its sides + Perimeter of circle

Quadrant of a circle is one fourth of a circle and there are 4 such quadrant of a circle, so eventually there is one complete circle in this figure.

The sides of this resultant figure = 30 - 14 = 16 cm

and 25 - 14 = 11 cm

So perimeter of this figure = 16 + 11 + 16 + 11 + Perimeter of circle

$\Rightarrow 54 + 2 \pi r\\\Rightarrow 54 + 2 \times \dfrac{22}{7} \times 7\\\Rightarrow 54 + 44 = 98 cm$

To find area of this figure = Area of rectangle - Area of circle

Area of rectangle = Length $\times$ Width

$\Rightarrow 30 \times 25 = 750\ cm^{2}$

Area of circle = $\pi r^{2}$

$\Rightarrow \dfrac{22}{7} \times 7^{2} = 154\ cm^{2}$

So, area of figure = 750 - 154 = 596 $cm^{2}$

2.11 A concert is performed for a crowd of 118

never [62]

Answer:

Number of Students who attended = 22

Number of Adults who attended = 34

Number of Children who attended = 62

Step-by-step explanation:

Total crowd at concert = 118

Cost of each adult's ticket = $20

Cost of each student's ticket = $16

Cost of each children's ticket = $11.50

The total revenue of the concert = $1745.00

Now, Let the number of students = k

So, the number of children = k + 40

So, number of adults = 118 - {k + (k + 40)}

= 118- 2k -40 = 78 -2k

So, the total revenue = Total revenue from {adults + students + children}

or, $1745.00 = (78 -2k)(20) + k(16) +(k+40)(11.50)

here, solving for the value of k :

12.5k = 2020 - 1745

or k = 275\12.5 = 22

So, the Number of students who attended = 22

Number of Adults who attended = 78 - 2k = 78 - 44 = 34

Number of children who attended = k + 40 = 22 + 40 = 62

NEED HELP ASAP!! GIVING BRAINLIEST TO BEST ANSWER FOR THESE 2 QUESTIONS! PLS HELPPPPPP

dedylja [7]

Answer:

9) $\\\frac{14}{16}$

10) $28\frac{5}{8}$

Step-by-step explanation:

$1\frac{3}{4}$ you change by multiplying 1 * 3 (the numerator) and adding 4 (the denaminator), putting the result (7) to the numerator and keeping the denaminator (4) = $\frac{7}{4}$

$\frac{7}{4} * \frac{2}{4} = \frac{14}{16}$

10) 7*4 = 28

so $28\frac{5}{8}$
