Answer:
C. 238π cm^3.
Step-by-step explanation:
Surface area = 2 * area of the circular ends + area of the curved length
= 2π r^2 + 2π r* l
= 2 π 7^2 + 2π 7 * 10
= 98π + 140π
= 238π cm^3.
Answer:
15 and 27 are composite
Step-by-step explanation:
prime numbers only factor into 1(x) and x(1)
13 = 1(13), 13(1)
15 = 1(15), 3(5), 5(3), 15(1)
17 = 1(17), 17(1)
27 = 1(27), 3(9), 9(3), 27(1)

Answer:
sin θ = 
Step-by-step explanation:
Given that,
cos θ = 
From the trigonometric functions,
cos θ = 
⇒ adjacent =
, and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
=
+ 
=
+ 
9 = 3 + 
= 9 - 3
= 6
x = 
Thus, opposite side = 
So that,
sin θ = 
= 
Therefore,
sin θ = 
Answer:
72 degrees.
Step-by-step explanation:
The angle marked as 72 degrees and the angle of JOK are considered vertically opposite angles in relation to each other. This relationship means that the angles are equal.
