Answer:

Volume = 175.93km ^3

Surface Area = 753.97km ^2

Step-by-step explanation:

Cylinder surface area =A=2πrh+2πr2

Volume = V=πr2h

We plug in

Area = 2 x π x 8km x 7km =2π 56 = 351.85km ^2

= 351 858 377 m^2

+ 2πr2 = 2 x π x 64 = 402.12km^2

Surface Area = 2π 56 + 2π x 64

402.12 + 351.85 =753.97km ^2 = 753 97 8377 m^2

Volume = π x 8 x 8 x 7 = 448π = 1407.43km ^2

= 140.743m^3

In the isosceles △ABC m∠ACB=120° and AD is an altitude to leg BC . What is the distance from D to base AB , if CD=4cm?

7nadin3 [17]

Correct answer is: distance from D to AB is 6cm

Solution:-

Let us assume E is the altitude drawn from D to AB.

Given that m∠ACB=120° and ABC is isosceles which means

m∠ABC=m∠BAC = $\frac{180-120}{2}=30$

And AC= BC

Let AC=BC=x

Then from ΔACD , cos(∠ACD) = $\frac{DC}{AC} =\frac{4}{x}$

Since DCB is a straight line m∠ACD+m∠ACB =180

m∠ACD = 180-m∠ACB = 60

Hence $cos(60)=\frac{4}{x}$

$x=\frac{4}{cos60}= 8$

Now let us consider ΔBDE, sin(∠DBE) = $\frac{DE}{DB} =\frac{DE}{DA+AB} = \frac{DE}{4+8}$

$DE = 12sin(30) = 6cm$
