Equivalent fractions have the same value even if written differently. The smallest common multiple of all the denominators in a group of fractions is the least common denominator. Fractions cannot be used to show the relationship between part of a group and the whole group.
Answer:
(0,2), (1,-3)
Step-by-step explanation:
Given:
The surface area of a right circular cone is 32 sq. cm.
Scale factor for enlargement = 3
To find:
The surface area of the new cone.
Solution:
We know that enlargement of a shape forms a similar shape and area of the similar shapes is proportional to the square of their corresponding sides.
Let the surface area of new cone be A and r be the radius of original cone
By cross multiplication, we get
The surface area of the new cone is 288 sq. cm.
Therefore, the correct option is C.
