Answer:
7.875......7.9.....or 8
Step-by-step explanation:
-3÷2×-21÷4= 7.875
63÷8=7.875
Answer:
radius r = 3 cm
height h = 10 cm
volume V = 282.743339 cm^3
lateral surface area L = 188.495559 cm^2
top surface area T = 28.2743339 cm^2
base surface area B = 28.2743339 cm^2
total surface area A = 245.044227 cm^2
In Terms of Pi π
volume V = 90 π cm3
lateral surface area L = 60 π cm^2
top surface area T = 9 π cm^2
base surface area B = 9 π cm^2
total surface area A = 78 π cm^2
Step-by-step explanation:
Cylinder Formulas in terms of r and h:
Calculate volume of a cylinder:
V = πr2h
Calculate the lateral surface area of a cylinder (just the curved outside)**:
L = 2πrh
Calculate the top and bottom surface area of a cylinder (2 circles):
T = B = πr2
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
Agenda: r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898
√ = square root
Answer:
x > 3
Step-by-step explanation:
-17x + 2 < -10x - 19
_____________
.Subtract 2 from both sides.
-17x + 2 - 2 < -10x - 19 - 2
____________________
.Simplify.
-17x < -10x - 21
__________________
.Add 10x to both sides.
-17x + 10x < -10x - 21 + 10x
____________________
.Simplify.
-7x < -21
_________________
.Multiply both sides by -1 (reverse the inequality).
(-7x)(-1) > (-21)(-1)
______________________
.Simplify.
7x > 21
_______________________
.Divide both sides by 7.
7x/7 > 21/7
_____________________
.Simplify.
x > 3
