≈ 33.3 cm²

Step-by-step explanation:

Given the linear ratio of 2 similar cones = a : b , then

ratio of their areas = a² : b²

Here the ratio of radii = 2 : 3 , thus

ratio of areas = 2² : 3² = 4 : 9

let x be the area of the smaller cone then by proportion

= ( cross- multiply )

9x = 300 ( divide both sides by 9 )

x = 33.33333

Thus

surface area of smaller cone ≈ 33.3 cm² ( nearest tenth )

the correct answer is x/3+10≥32

hope this !

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
