what is the surface area of cone with a diameter of 10 centimeters and a slant height of 12 centimeters round your answer to the
Oduvanchick [21]

The surface area of the cone is 266.9cm^2

Explanation:

The diameter of the cone is 10 cms

Thus, the radius of the cone is given by

r=\frac{d}{2} =\frac{10}{2} =5

The slant height of the cone is 12 cms

The formula for surface area of the cone is given by

$S A=\pi r^{2}+\pi r l$

Substituting the values, we get,

$S A=(3.14)(5)^{2}+(3.14)(5)(12)$

$S A=(3.14)25+(3.14)(60)$

SA=78.5+188.4

SA=266.9cm^2

Thus, The surface area of the cone is 266.9cm^2

Trava [24]

Answer:

1)   x = 4  2)   x = 4   3)  x = -4   4)   x = 3   5)   x = 5   6)   x = 9   7)   x = -8  

8)   x = 11   9)   x = -5   10)   x = -4

Step-by-step explanation:

Alternate Exterior and Alternate Interior angles are equal to each other.  Just set the numbers or equations the give you equal to each other.

Question 1:             Question 2:                 Question 3:               Question 4:

33x+3=135              120=31x-4                    120=x+124                 40x+5=42x-1

33x=132                  124=31x                        -4=x                           6=2x

x=4                          x=4                                x= -4                          x=3

Question 5:             Question 6:             Question 7:             Question 8:

20x+4=19x+9           11x= -9+12x               80=x+88                 10x+20=12x-2

-5= -x                        -x = -9                       -8 = x                      22=2x

x=5                            x= 9                          x= -8                       x=11

Question 9:              Question 10:

70=x+75                   130=x+134

-5 = x                         -4 = x

x = -5                         x= -4
