Answer:
125.660 cm^2
Step-by-step explanation:
Surface area of a right cylinder is A=2πrh+2πr^2
π= 3.14
h= 8 cm
r= 2 cm
A=(2)(3.14)(2)(8) + (2)(3.14)(2)^2
Answer:
the answer should be -4
Step-by-step explanation:
-4 squared would be 8. 3 multiplied by -4 would be -12. 8 + -12 = -4. -4 + 4 = 0
Ah, I think you may have forgotten to include something in your question, but any letters are likely the variables of which they speak.
