Answer:
163.75
Step-by-step explanation:
a scale factor applies normally to lengths (one-dimensional sizes).
and the perimeter is calculated just by lengths (the side lengths).
so, we can apply the scaling factor directly to the perimeter.
perimeter of DEF = 5/2 × perimeter of ABC = 5/2 × 65.5 =
= 163.75 ft
what was step 1 ? we did not need it ?
Answer:
La fórmula para el área total de superficie de un cono recto es T. S. A. = π rl + π r 2 . Ejemplo 2: Encuentre el área lateral de superficie de un cono recto si el radio es de 6 pulgadas y la altura de inclinación es de 10 pulgadas.
A=P(1+rt)
A=500(1+6.6%)^2
A=$568.18
Answer is D
2:4:2.....added = 8
2/8 (56) = 112/8 = 14
4/8 (56) = 224/8 = 28
2/8 (56) = 112/8 = 14
14:28:14
