Answer:

The answer to your question is SA = 150.72 in²

Step-by-step explanation:

Data

Surface area = ?

height = 5 in

radius = 3 in

pi = 3.14

Formula

SA = 2πr² + 2πrh

Process

1.- Calculate the area of the bases

-Substitution

Area = 2(3.14)(3)²

-Simplification

Area = 2(3.14)(9)

-Result

Area = 56.52 in²

2.- Calculate the lateral area

-Substitution

Area 2 = 2(3.14)(3)(5)

-Result

Area 2 = 94.2 in²

3.- Calculate the total area

SA = 56.52 + 94.2

SA = 150.72 in²

Answer:

169 meters

Answer:

x = 30

Step-by-step explanation:

Since this is a right triangle,

90 = (x + 20) + (x + 10)

90 = x + x + 20 + 10

90 = 2x + 30

90 - 30 = 2x

60 = 2x

60/2 = 2x/2

30 = x

Check:

x + 20

30 + 20 = 50

x + 10

30 + 10 = 40

50 + 40 = 90

Hope this helps!
