Its perimeter would equal 7/8 inch (1/4+1/4=2/4=4/8+3/8=7/8)

In the diagram m angle ACB = 61<br> Find m angle BCD

Marina86 [1]

we are given that

angle(ACF)=90

angle(ACB)=61

sum of all angles along any line is 180

so, we get

angle(ACF)+angle(ACD)=180

we can plug value

90+angle(ACD)=180

angle(ACD)=90

now, we can use formula

angle(ACD)=angle(ACB)+angle(BCD)

now, we can plug values

and we get

90=61+angle(BCD)

90-61=61-61+angle(BCD)

angle(BCD)=29................Answer

The cost of painting the total outside surface of a closed cylindrical tank at 60 paise per meter squae is Rs237.60. The height

valkas [14]

Answer:

$volume=509.25 dm^{3}$

Step-by-step explanation:

Curved surface area= $\frac {237.6}{0.6}=396 dm^{2}=2\pi R(R+H)$ where R is radius and H is height

Since H=6R then curved surface area= $2\pi R(R+6R)=14\pi R^{2}$

Therefore,

$396 dm^{2}=14\pi R^{2}$ and making R the subject

$R=\sqrt {\frac {396}{14\pi}}=\sqrt {(9.003622)}= 3.000604 m$

Therefore, H=6R=6*3.000604=18.00362 m

$Volume=\pi R^{2}H=\pi*3.000604^{2}*18.00362=509.2453 dm^{3}$

Therefore, $volume=509.25 dm^{3}$
