Answer:
The total surface area of the the cylinder is 640.56cm², surface are is always give in cm² not in cm³ b/c cm³ indicates the volume of the cylinder not the surface area.
Step-by-step explanation:
Hello!
. SA=2πr(r+h) ,or 2πr²+h(2πr)
- SA=2(3.14)(6cm)(6cm+11cm)
- SA=6.28(6cm)(17cm)
- SA=37.68cm(17cm)
- SA=640.56cm²
Answer:
The new price is 11.99
Step-by-step explanation:
First find the mark down
14.99 * 20 %
14.99 * .20
2.998
3.00
Subtract the markdown from the price
14.99-3.00
11.99
The new price is 11.99
You can only add/subtract like terms so:
2a+ab+2b+4a^2-3ab+9
2a-2ab+2b+4a^2+9 (the only like terms were ab and -3ab)
The next term in this sequence would be 18.
Because the sum of the angles in the triangle is 180°...
(x+6)+(3x-16)+x=180
5x-10=180
5x=190
x=38°
Because we want m<M, we want 3x-16.
3x-16=3(38)-16=98°
answer: 98°
