Answer:
a c
Step-by-step explanation:
Answer:
(11√3)/3
Step-by-step explanation:
In order to solve for the variable, you will need to use a trig function. In this case, you will need to use the trig function tangent.
Tan = opposite/adjacent
⇒ Tan 30° = x/11
⇒ 11 · Tan 30° = x
⇒ (11√3)/3 = x
Everything about number one is because it's a half of circle so its area = 1/2 ¶r^2 and its perimeter = ¶r
The best answer would be
2.4 x 10 ^6
10 to the sixth power multiplied by 2.4
