Let's find the reciprocal.
6/1 is the fraction of 6. Flipped is 1/6.
The reciprocal is 1/6.
The opposite means either positive or negative. Since it's already positive, it'll turn negative.
-1/6.
Answer:
4) 120π cm^2
5) 56π cm^2
6) 32π cm^2
Step-by-step explanation:
Surface Area of Cylinder = 2π
+ (2πr)(height)
(will use variable h for height)
4)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 11 cm
2π
+ (2π)(4)(11)
= 2π(16) + 2π(44)
= 32π + 88π
= 120π cm^2
5)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 6 cm
2π
+ (2π)(4)(6)
= 2π(16) + 2π(12)
= 32π + 24π
= 56π cm^2
6)
diameter = 6 cm
r = 0.5(diameter) = 0.5(6) = 3 cm
height = 7 cm
2π
+ (2π)(3)(7)
= 2π(9) + 2π(7)
= 18π + 14π
= 32π cm^2
