The total height of three of thumbelina’s sisters is 180 cm. if the heights of the three sisters are in the ratio 4: 3: 5, find the height of the smallest sister.

The height of the smallest sister is 45 cm

Step-by-step explanation:

We are given that the heights of the three sisters are in the ratio 4:3:5

Let the ratio be x

So, The heights of three sisters are 4x,3x and 5x

We are given that The total height of three of Thumbelina’s sisters is 180 cm.

So,

Height of smallest sister = 3x=3(15)=45 cm

Hence The height of the smallest sister is 45 cm

i do not know the answer i am sorry

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
