The surface areas of two similar solids are 441 cm² if the volume of the smaller solid is 250 cm³ what is the volume of the larger solid to the nearest cubic centimeter

The complete question is;

The surface areas of two similar solids are 441 cm² and 225 cm². If the volume of the smaller solid is 250 cm³ what is the volume of the larger solid to the nearest cubic centimeter

volume of the larger solid;V = 686 cm³

Step-by-step explanation:

We are given that;

Area of smaller solid = 225 cm²

Area of bigger solid = 441 cm²

Now, let r be the ratio of similarity;

Thus ratio of big to small solid is gotten from;

441 = 225 x r²

441/225 = r²

r =√441/225

r = 21/15 = 7/5

Now, let V be the volume of the larger solid.

Thus;

V = r³(250)

V = (7/5)³(250)

V = 686 cm³

answer: (1,3) (3,-1) (5,-5) ?

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
