Volume = 1/3 * pi * r^2 * h
             = 1/3 * pi * 8^2 * 1.5     ( radius = 1/2 diameter = 1/2 * 16 = 8)
             =  130.7 km^3 Answer

Answer:

130.624km^{3}

Step-by-step explanation:

Given : A volcano in  shape of a cone has a diameter of 16 km and a height of 1.95 km.

To Find : Volume of Volcano.

Solution :

Since we are given that volcano is in shape of cone .

So, Formula of volume of cone : \frac{1}{3} \pi r^{2}h

Height = 1.95 km.

Diameter = 16 km

Radius (r) = Diameter/2 = 16/2 =8 km

π = 3.14

Substituting all values in formula

Volume of volcano:

= \frac{1}{3} *3.14 (8)^{2}*1.95

⇒ \frac{391.872}{3}

⇒ 130.624km^{3}

Thus , The volume of volcano is  130.624km^{3}  i.e. 131 cubic km. nearest to whole number

Answer:

(a) x=\dfrac{\pi}{8},\dfrac{3\pi}{8},\dfrac{9\pi}{8},\dfrac{11\pi}{8}

(b) x=\dfrac{3\pi}{2},\dfrac{\pi}{6},\dfrac{5\pi}{6}

Step-by-step explanation:

It is given that 0\leq x\leq 2\pi.

(a)

\sqrt{2}\sin 2x=1

\sin 2x=\dfrac{1}{\sqrt{2}}

\sin 2x=\dfrac{\pi}{4}

2x=\dfrac{\pi}{4},\dfrac{3\pi}{4},\dfrac{9\pi}{4},\dfrac{11\pi}{4}     [\because \sin x=\sin y\Rightarrow x=n\pi+(-1)^ny]

x=\dfrac{\pi}{8},\dfrac{3\pi}{8},\dfrac{9\pi}{8},\dfrac{11\pi}{8}

(b)

\csc^2 x-\csc x-2=0

\csc^2 x-2\csc x+\csc x-2=0

\csc x(\csc x-2)+1(\csc x-2)=0

(\csc x+1)(\csc x-2)=0

\csc x=-1\text{ or }\csc x=2

\sin x=-1\text{ or }\sin x=\dfrac{1}{2}         [\because \sin x=\dfrac{1}{\csc x}]

x=\dfrac{3\pi}{2}\text{ or }x=\dfrac{\pi}{6},\dfrac{5\pi}{6}

Therefore, x=\dfrac{3\pi}{2},\dfrac{\pi}{6},\dfrac{5\pi}{6}.
