Cylinder A has radius r and height h as shown in the diagram. Cylinder B has radius 4r and height 4h. How many times greater is the surface area of Cylinder B than the surface area of Cylinder A?

Pls help WILL GIVE BRAINLIEST

16 times

Step-by-step explanation:

Since the sides are in the same ratio, i.e

1 : 4

The cylinders are similar

(Ratio of sides)² = Ratio of areas

4² = 16

Step-by-step explanation:

Step 1:  Make a ratio of the sides

Side of Cylinder A : Side of Cylinder B

            1                  :                4

Step 2:  Find the ratio of the area

← Ratio of Side

← Ratio of Area

← Ratio of Area

 The area of Cylinder B is 16 times greater than Cylinder A

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
