Answer: $1296
Step-by-step explanation:
Surface area of s sphere = 4πx r^2
Diameter = 1/2 radius
Surface area = 4π x 12^2
= 1809.56 cm^2 = 18.096 m^2
Material required = 71.62 x 18.096
= $1296
3.5 because if you divide 252 by 72 you get 3.5 :D
Answer:
hello : sin(θ) = 4/25
Step-by-step explanation:
you know : cos²(θ) + sin²(θ) =1 and : cos(θ) = - 3/5
(-3/5)² + sin²(θ) =1
9/25 + sin²(θ) =1
sin²(θ) =1 -9/25
sin²(θ) = 16/25
sin(θ) = 4/25 or sin(θ) = - 4/25
in quadrant 2 : sin(θ) > 0
so : sin(θ) = 4/25
Step-by-step explanation:
Hey, there!!
a. (-12)×(-11)×10
Here, (-)×(-)=(+)
(-12)×(-11)=132
so,
=132×10
=1320.
For b.
(-25)×(-8)×(-2)
(-)×(-)=(+)
(-25)×(-8)=200
so,
=200×(-2) { (+)×(-)=(-)}.
= -400.
Therefore, the answer of a. no. is 1320, and no. b is (-400).
