Step-by-step explanation:
24/27 = (24 ÷ 3)/(27 ÷ 3) = 8/9
Find the area of the circle using A=pi * r^2 and then divide that answer by 2 and that will get you the area of the semicircle.
Answer:
<em>The surface area is multiplied by 4/9.</em>
Step-by-step explanation:
<u>Surface Area of a Cone</u>
Being r the radius and l the slant height of a cone, then its surface area is

Now let's think both the radius and the slant height are multiplied by the same factor k, i.e.
r'=kr
l'=kl
The new surface area is


The new surface area is the
times original SA. Since k=2/3, then

The surface area is multiplied by 4/9.
