Answer:
2155.1 m^3
Step-by-step explanation:
area= pi* r ^2 * h =pi * 7^2 *14 = 2155.1 m^3
Answer:
area=πr²=3.14×4²=50.24ft²
Answer:
f(-3) = 21
Step-by-step explanation:
To solve this, you can replace all x's with -3 and then solve to find the answer.
f(x) = x^2 - 4x
f(-3) = -3^2 - 4(-3)
f(-3) = 9 - (-12)
f(-3) = 21

Answer:
<h2><u>0.384</u></h2>
Step-by-step explanation:
By Pythagoras Theorem,
OM = √(4² + 3²) = √(16 + 9) = √25 = <u>5</u>
And,
OL = √(12² + 5²) = √(144 + 25) = √169 = <u>13</u>
Now,
sin L = 
= 
= <u>0.384</u>
