Answer:
Surface area of cylinder = 91.2π cm²
Volume of cylinder = 57.6π cm³
Step-by-step explanation:
Given:
Height of cylinder = 1.6 cm
Radius of cylinder = 6 cm
Find:
Surface area of cylinder
Volume of cylinder
Computation:
Surface area of cylinder = 2πr[h+r]
Surface area of cylinder = 2π(6)[1.6+6]
Surface area of cylinder = 2π(6)(7.6)
Surface area of cylinder = 91.2π cm²
Volume of cylinder = πr²h
Volume of cylinder = π(6)²(1.6)
Volume of cylinder = π(36)(1.6)
Volume of cylinder = 57.6π cm³
Answer:
81y^4 - 16x^2, difference of squares.
Step-by-step explanation:
So we need to expand the following product:
(9y2-4x)(9y2+4x) = 9y2*9y2 + 4x*9y2 - 4x*9y2 -4x*4x = 81y^4 - 16x^2
And this type of product is the difference of squares.
Answer: They are only 5 heart remaining.
Step-by-step explanation:

Line DG is 24.5. So DO +DG= 24.5
(3x+4) + (5x-1.5) =24.5 then combine like terms.
8x+2.5=24.5
-2.5. -2.5
8x = 22 then divide both sides by 8
X=2.75.
To find DO and OG plug in the value of X and solve
DO
3(2.75) +4
8.25+4 = 12.25
OG
5(2.75) -1.5
13.75 - 1.5= 12.25
