Answer:
The answer to your question is 9923 cm²
Step-by-step explanation:
Data
radius = 30.8 cm
height = 20.5 cm
Surface area = ?
Process
1.- Write the formula to calculate the surface area of a cylinder
SA = 2πr² + 2πrh
2.- Substitution
π = 3.14
SA = 2(3.14)(30.8)² + 2(3.14)(30.8)(20.5)
3.- Simplification
SA = 5957.459 + 3965.192
4.- Result
SA = 9922.65 cm² or SA = 9923 cm²
I beleive the system of equations would be:
a+b=4000
0.1a+0.04b=352
I cant say for sure because the question did not list the cost of a and b together but rather the number of both items together
Answer:
y = 1/25
Step-by-step explanation:
Reciprocal of y^(1/2) : 1/y^(1/2)
1/y^(1/2) = 5
y^(1/2) = 1/5
y = (1/5)^2
Answer:
triangle y= -3, triangle x= 5 M= -1 1/2
Step-by-step explanation:
actually I used the app that my teacher gave me in 7th grade so I'm gonna give it to you Just look up slope calculator and it says OMNI calculator
