Answer:

Step-by-step explanation:

<h2>Cone:</h2>

    diameter = 12 cm

                  r =  12 ÷ 2 = 6 cm

                 h = 6 cm

      \sf \boxed{\text{\bf Volume of cone = $\dfrac{1}{3} \pi r^2h$ }}

                                    \sf = \dfrac{1}{3}*3.14*6*6*6\\\\ = 226.08 \ cm^3

To find the surface area, we need to find the slant 'l'

       \sf l = \sqrt{h^2+r^2}\\\\       =\sqrt{6^2+6^2}\\\\        = \sqrt{36+36}\\\\ =\sqrt{72}\\\\= 8.49 \ cm

       \sf \boxed{\text{\bf Total surface area of cone = $\pi r(r+l)$}}

                                                         = 3.14 * 6 * (6 + 8.49)

                                                        = 3.14 * 6 * 14.49

                                                        = 273 cm²

3b - c +5 if c= - 4, b=2.
AnnZ [28]

Answer:

15

Step-by-step explanation:

To find the answer, plug the values of each variable into the equation and simplify. It may be easiest to plug one variable in at a time, simplify, then plug the next variable in. Remember, if the equation is asking you to subtract a negative number, the negatives cancel and you want to add the numbers.

b = 2          c = -4

3b - c + 5                                      <----- Original expression

3(2) - c + 5                                    <----- Plug 2 in for "b"

6 - c + 5                                        <----- Multiply 3 and 2

11 - c                                              <----- Add 6 and 5

11 - (-4)                                           <----- Plug -4 in for "c"

15                                                  <----- Add 11 and 4
