Answer:
200π
Step-by-step explanation:
Surface area is abbreviated to SA
TOTAL SA of cone = Base area + πrl
Base area = πr² = π x 8² = 64π
Curved SA = πrl = π x 8 x l
to work out l, use pythagoras theorem: √(15)² + (8)² = 17
so, curved SA = π x 8 x 17 = 136π
Total SA of cone = 64π + 136π = 200π

Answer:
Step-by-step explanation:
<em>The mode is the most repeated data in the set.</em>
According to the graph, the most repeated number is 3. There are four of 3's, three 2's and 4's and two 2's.
The mode is 3.
Answer:
12x^2 -5x - 3
Step-by-step explanation:
( 4x - 3)( 3x + 1 )
distribute
12x^2 + 4x - 9x - 3
combine like terms
12x^2 - 5x - 3
Hope this helps!!!
