Answer:
SA = 108π cm²
Step-by-step explanation:
The surface area (SA) of a sphere is calculated as
SA = 4πr² ( r is the radius )
Thus the SA of a hemisphere is
SA =
× 4πr² = 2πr²
The area of the circular base = πr²
Then total SA is
SA = 2πr² + πr² = 3πr² = 3π × 6² = 3π × 36 = 108π cm²
Answer:
(x+6)*3
Step-by-step explanation:
You will need to do this equation simply; and in order for that matter.
So you need to use the brackets so you know what comes first.
Remember BIDMAS or BODMAS
BIDMAS: BODMAS:
Brackets Brackets
Indices Order --- (These mean the same thing)
Divide Divide
Multiply Multiply
Addition Addition
Subtraction Subtraction
As you can see the brackets come first, so you do what is INSIDE the brackets before anything. (x+6)
To finish, you will need to multiply, but as it is an unknown, you don't know what to multiply the 3 by.
<u>So x, add 6, then times by 3 = (x+6) *3</u>
