Answer:
<em>V= 1/3(π.r².h)</em><em> </em><em>formula</em>
= 1/3×( 22/7 × 7²×9)
= 1/3× (22/7 × 49 × 9)
= 1/3×(22×7×9)
=1/3× (154×9)
=1/3× 1386
= <em>462 cubic </em><em>yards</em>
Step-by-step explanation:
Note:
π = 3,14 or 22/7
in trigonometry the value of π is 180 °
15 8/100, or 15 4/50 in simplified version.
I hope this helps, please Brainliest me, and have a great day! :D

Answer:
f = 3
Step-by-step explanation:
Given the equation cos(22f − 1) = sin(7f + 4), the following steps must be followed in order to get the value of f;
From the trigonometry identity, sin(90-theta) = cos theta.
cos(22f-1) = sin (90-(22f-1))
cos(22f-1) = sin (90-22f+1)
cos(22f-1) = sin (91-22f)... 3
substituting eqn 3 into the original equation given, we will have;
sin (91-22f) = sin(7f + 4)
91-22f = 7f+4
7f+22f = 91-4
29f = 87
f = 87/29
f = 3
