Answer:

1306.24 cm².

Step-by-step explanation:

From the diagram given above, we obtained the following information:

Radius (r) = 13 cm

Pi (π) = 3.14

Slant height (l) = 19 cm

Surface Area (SA) =.?

The surface area of the cone can be obtained as follow:

SA = πr² + πrl

SA = πr ( r + l)

SA = 3.14 × 13 ( 13 + 19)

SA = 40.82 (32)

SA= 1306.24 cm²

Therefore, the surface area of the cone is 1306.24 cm².

2-5(h+3)=-28 What does h equal? SHOW YOUR WORK
fiasKO [112]

3(x+1) = 2(x-8) + 3. First, remove the parentheses by distributing (multiplying out the numbers):


3x + 3 = 2x - 16 + 3.

Then, combine any like terms on the same side of the equals sign;


3x + 3 = 2x -13.

Then, move the like terms on opposite sides of the equals sign to the same side of the equals sign (don't forget to change the signs)..


3x -2x = -13 - 3.

Then combine the like terms on the same side of the equals sign again.. x = -16 .
