Answer:
(b) Each side of the original triangle is 2 times the length of each side of the scale drawing.
Step-by-step explanation:
If the smaller is 1/2 the larger, then the larger is 2 times the smaller. The original triangle's sides are 2 times those of the scale drawing.
The area of the base is
.. A = πr^2
The lateral area is
.. A = πrh . . . . . where h is the slant height
The total area is
.. π(r^2 +rh) = πr(r +h)
total surface area = 3.14*(5 m)*(5 m +11 m) = 251.2 m²
Answer:(x+6) (x+6)
(x+6)^2
Step-by-step explanation:
36+12x+x^2
x^2 +12x +36
What 2 numbers multiply to 36 and add to 12
6*6 = 36
6+6 =12
(x+6) (x+6)
(x+6)^2
