Answer:
a) Volume = 2/3 r³
Volume = 2/3 × 22/7 × 14 × 14 × 14 = 5749.3 cm³
b) Total surface area = 3r²
Area = 3 × 22/7 × 14 × 14 = 1848 cm²
Answer:
The fountain is 3.43 m high.
Explanation:
Circumference of the pool = 15 m.
C = 2r
where C is the circumference and r its radius.
r =
=
r = 2.3864
radius of the pool = 2.40 m
So that the height of the fountain, h, can be determined by applying trigonometric function.
Tan θ =
Tan 55 =
h = Tan 55 x 2.4
= 1.4282 x 2.4
= 3.4277
h = 3.43 m
The height of the fountain is 3.43 m.
