1) The angle of elevation of the top of the building at a distance of 50 m from its foot on a horizontal
seropon [69]

Answer:

the height of the building is 86.6m

Step-by-step explanation:

In the right triangle, the height which we are looking for is the opposite side, since it is opposite to the angle 60°

Now we need to find the height of the building

tanθ = Opposite side/Adjacent side

tan 60° = Opp side/Adj side

1.7321 = Opp side/50

1.7321 x 50 = Opp side

Opp side = 50 x 1.7321

Opp side = 86.6 m

Therefore, the height of the building is 86.6m.

The radius of a cylinder is increased by 5 percent. Given that the height is constant, find the percentage increase in volume. ​
telo118 [61]

Step-by-step explanation:

Volume =pir^h

V1=pi r1^h

V2=pir2^2h

Now,V1/V2=r1^2/r2^2

v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)

v1/v2=1/1.1025

v1/v2=0.907

(v1/v2-1)=0.0907×100%

(v1-v2)/v2=9.07%

increase in volume is 9.07%
