Answer:
C. 120°
Step-by-step explanation:
length of arc = 4π cm
r = 6 cm
central angle = s/r
=> central angle = 4π/6
=> central angle = 2π/3 radians
In degrees,
central angle = (2π/3)(180/π) = 120°
hope this helps and is right. p.s i really need brainliest :)
Answer:
972π in³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ← r is the radius
Here r = 9, thus
V = π × 9³ = π × 729 ( divide 3 and 729 by 3 )
= 4π × 243
= 972π in³
Answer:
can I have an example?????
Answer:
-2.453
Step-by-step explanation:
sqrt(6) * sqrt(2) = 3.461
sqrt(6) * -2 = -4.899
sqrt(3) * sqrt(2) = 2.449
sqrt(3) * -2 = -3.464
sum of numbers equals
-2.453
