Answer:
-7/18
Step-by-step explanation:
cos(2x) = 1 - 2sin²x
cos(2x) = 1 - 2(5/6)²
= 1 - 2(25/36)
= 1 - 25/18
= -7/18
Answer:
Step-by-step explanation:
area of sector = {Ф ( in degrees)/360}πr²
Ф = 60
π=3.14
r=10
area = (60/360) x 3.14 x 10²
= (1/6)x3.14 x100 = (1/6)x314= 314/6 = 52.33
Answer: 268.08in³
Formula:
V=<u>4 </u>π r³
3
d= 2r
Solving for V:
V=<u>1</u> π d³=<u>1</u>·π·83≈268.08257in³
