80
Step-by-step explanation:
5×6 = 30 and 30×8 = 240 divide that by three you get 80
X-5= 20
x-5= -20
Absolute value makes a negative positive, so when you are solving x-5 could have been 20 originally or -20 originally. Solve for both.
The answer is
The diameter is 4 (2) = 8 and height is 10(2) = 20
For the sides, use area of a cylinder = ph
p = 8 pi cm, ht = 20 cm. A = 160 pi sq cm
Base are 2 circles, each with radius 4 pi
Area = pi r^2 = 16 pi (times 2 circles) = 32 pi sq cm
