Find the surface area. Use 3.14 for pie

The surface area is 1,580.99 in²

Step-by-step explanation:

Known :

Diameter (d) = 19 in

Height (h) = 17 in

Asked :

Surface Area (Sa) = ...?

Answer :

Radius (r) = ½ d = ½ × 19 = = 9,5 cm

Tube Surface Area Formula :

=

= 3.14 × 19 × (9,5 + 17)

= 59.66 × 26.5

= 1,580.99 in²

So, the surface area is 1,580.99 in²

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
