a. using the same ratios:

26 : x = 8 : 12

x = (26*12)/8

x = 312/8

x = 39 $

b. using the same ratios:

5 : x = 20 : 10

x = (5*10)/20

x = 50/20

x = 2,5$

c. Sinea:

5 : 12 = 40 : x

x = (12*40)/5

x = 480/5

x = 96$

Ren:

10 : 20 = 40 : x

x = (40*20)/10

x = 800/10

x = 80$

Sinea would spend more money because the ratio of her money spend on souvenirs and snacks is 12/5 = 2,4 which is bigger than in Ben's case, where it's 20/10 = 2, hence SInea would spend more money.

The volume of clay used to build a cylindrical pillar with a height of 9 centimeters is 324π cubic centimeters. What is the area

elena-s [515]

Given:
V = 324 cu cm
h = 9 cm

Since the formula for the volume of a cylinder is V = AreaBase*height

AreaBase = V/height = 324cu cm/ 9 cm
AreaBase = 113.04 square centimetres

Therefore, the area of the pillar in square centimeters is 113.04.
