Answer:

As = 2112 cm²

Step-by-step explanation:

given:

A cylinder has a circular base radius 14cm and height of 10cm.

find:

the total surface area of the cylinder. [take pie 22/7] *

solution:

<u>surface area (As) = 2πrh + 2πr²</u>

where r = 14 cm; h = 10 cm; π = 22/7

plugin values into the formula:

As = 2 (22/7) 14 (10) + 2 (22/7) 14²

As = 880 + 1232

As = 2112 cm²

Answer:

ii) curved surface area =2 pie rh

2*22/7*14*21

1548 cm2

iii) total surface area=2 pie r(r+h)

2*22/7*14(14+21)

2780

iv) volume of cylinder=pie r2h

22/7*14*14*21

Herman is traveling 125 miles from his house to the beach by car. Herman plans to stop for lunch when the ratio of the distance

aliya0001 [1]

Answer:

250 miles

Step-by-step explanation:

The given distance between the house and the beach is 125 miles.

Let $x$ miles be the distance between the house and the lunch stop.

So, at the time of the lunch stop, he already traveled $x$ miles, the remaining distance is the distance between the lunch stop and the beach.

Let $y$ miles be the remaining distance, so

$y=125-x.$

Give that the ratio of the distance he has traveled, $x$ , to the distance he still has to travel, $y$ , is $2:3$ ,i.e

$x:y=2:3$

$\Rightarrow \frac x y =\frac 2 3$

$\Rightarrow \frac {x}{125-x}=\frac 2 3$

$\Rightarrow 3\times x=2\times(125-x)$

$\Rightarrow 3\times x=2\times125-2\timesx$

$\Rightarrow 3 x=250-2x$

$\Rightarrow 3x-2x=250$

$\Rightarrow x=250$

Hence, the distance traveled by Herman when he stops for lunch is 250 miles.

Answer:

0.1875

Step-by-step explanation:

σM=σ/√N

=8/√7500

=8/86.608

=0.092

Z=(x-μ)/σ/√N

=(25.5-36)/8/√7500

=-10.5/0.0092=-1141.304

Z score = -1.3125

=(27-36)/8/√7500 =

=9/0.0092=978.261

Z score= -1.125

-1.125-(-1.3125)=-1.125+1.3125)= 0.1875

The probability that the sample mean will be between 25.5 and 27 years

P(between 25.5 and 27) = 0.1875
