None of above i think not sure
Given:
Height of cylinder = 12 cm
Diameter of cylinder = 6 cm
To find:
Surface area of the cylinder
Solution:
Radius = 6 ÷ 2 = 3 cm
Surface area formula:

Substitute the given values.


= 286.2 cm²
The surface area of the cylinder is 286.2 cm².
Answer:
(f + g)(x) = x² - x + 6
Step-by-step explanation:
Step 1: Define
f(x) = x² + 1
g(x) = 5 - x
Step 2: Find (f + g)(x)
(f + g)(x) = x² + 1 + 5 - x
(f + g)(x) = x² - x + 6
Answer:
Option B is the correct answer
Step-by-step explanation:
After removing squares with side 4 inch long, the open box will have following dimensions:
Length = x + 9 - 4 - 4 = (x + 1) in
Width = x - 4 - 4 = (x - 8) in
Height = side of square = 4 in
It is given that volume of the open box is 64 cubic inches.
