Answer:
B. 54π units ²
Step-by-step explanation:
solution:
given,
Radius (r) = 3
(l) = 15
we know that,
T.S.A. of cone = πr( r + l )
= π × 3(3 + 15)
= π × 3 × 18
= π × 54
= 54π units ²
Answer:
x = -6
Step-by-step explanation:
In this equilateral triangle, all sides are congruent. Thus, all angles are generally congruent as well. This is a 60-60-60 triangle. So,
66 + x = 60
x = -6
Answer:
C: All real numbers.
Step-by-step explanation:
Domain means the interval of x=values that the function resides in. Since this quadratic function can go to both positive and negative infinity, there are no limits to the x-values so therefore the domain is all real numbers.
