Answer:
1155.52 cm²
Step-by-step explanation:
SA = LSA (Pb x h) + 2B
- r = 8 cm, h = 15, π (pi) = 3.14
Lateral Surface Area (LSA) = Pb (Perimeter of base) x h (height)
8 x 2 = 16 x 15 = 240 x 3.14 = 753.6
Area of the Base x 2 = πr² x 2
8² x 3.14 = 64 x 3.14 = 200.96 x 2 = 401.92
753.6 + 401.92 = 1155.52
Answer:
Surface Area of the Cylinder is 1156.11
Step-by-step explanation:
To find the Surface Area of a Cylinder, the equation given is A = 2πrh+2πr2
Given the radius and height of the cylinder, we plug those numbers into the equation to get;
A = 2π(8)(15)+2π(8)2
= 1156.11

Answer:
A constant of $20 can be multiplied by the number of months to find the amount in the account.
Step-by-step explanation:
4×20=80
7×20=140
Answer:
(-4,4)
Step-by-step explanation:
-5x-10y=-20
10x+10y=0
divide both sides by 2
-5x-10y=-20
5x+5y=0
that makes
-5y=-20
divide both sides by -5
y=4
now substitute 4 for y
10x+10 x 4=0
multiply
10x+40=0
subtract
10x=-40
divide
x=-4
Answer:
y= 3x
Step-by-step explanation:
When in aqueous solution, K2CrO4 dissociates into ions. It dissociates into:
K2CrO4 = 2K+1 + CrO4-1
We do as follows:
Molarity = mol / L = 0.38 g/g solution ( 1.37 g/mL ) ( 1 mol / 194.19 g ) ( 1 mol CrO4-1 / 1 mol K2CrO4 ) ( 1000 mL / 1 L ) = 2.68 M
