Answer:
The surface area of the cylinder is
Step-by-step explanation:
The surface area of a cylinder is express
where is the radius of the cylinder and its height
Therefore, if the radius of the cylinder is
and its height
the surface area should be
Answer:
$342
Step-by-step explanation:
370+310+380+340+310=1710
1710/5=342
Answer:
4
Step-by-step explanation:
Answer:
distance TS ≈ 19 m (nearest meter)
Step-by-step explanation:
The point T is on the horizontal ground and the angle of elevation of the top R of a tower is 63° and the height of the tower is 38 m high. The illustration forms a right angle triangle. The height RS of the tower is the opposite side of the triangle formed. The hypotenuse side of the triangle is the point from the ground T to the top of the tower R. The adjacent side of the triangle is the side TS.
using tangential ratio
tan 63° = opposite/adjacent
tan 63° = 38/adjacent
cross multiply
adjacent tan 63° = 38
divide both sides by tan 63°
adjacent side = 38/tan 63°
adjacent side = 38/1.96261050551
adjacent side = 19.3619670807
distance TS ≈ 19 m (nearest meter)
I am pretty sure the answer is 30 sorrry if I am wrong
