When baking a cake, you have a choice of the following pans: a round cake pan that is 2 inches deep and has a 7 inch diameter a
ruslelena [56]
Round pan volume is:
3.14•r^2•h
D=7 so r=3.5 in
3.14• (3.5^2)•2 = 76.97 in^3

Rec. pan vol. is :
9•6•2= 108 in^3

Rec. Pan is larger because 108 in^3 is > 76.97 in^3 :) .

The icing that will be needed to frost the round cake pan is:
We need to find the surface area:
S.A= 3.14r^2 + 2 • 3.14•r • h .... 3.14 is the value of PI
So, S.A= 3.14• 3.5^2 + 6.28• 3.5• 2= 82.47 in^2 the icing that'll be needed to frost the round cake pan.

Icing that will be needed for the rec. cake pan is:

2•9•2=36 in^2
6•9•2= 108in^2
6•2= 12 in^2
S.A= 156 in^2 the icing needed to frost the rec. cake pan .... the S.A of all sides except the bottom one :).

Good luck ;-)

bezimeni [28]

Answer:

D

Step-by-step explanation:

<em>Midpoint Formula:</em>

\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}

\frac{3+1}{2} ⇒ \frac{4}{2} ⇒ 2

\frac{8+-4}{2} ⇒ \frac{8-4}{2} ⇒ \frac{4}{2} ⇒2

(2,2)
