Iwant to know how to calculate the radius, im very confused.

the cones below are similar, although not drawn to scale
(smaller cone) (larger cone)
height is 12 ft height is 15 ft r
radius is 8 ft radius not given

what is the lenght of the radius of the larger cone?

a= 10ft
b=11ft
c=12ft
d=13ft

1 0 10

a 10 ft

Step-by-step explanation:

To find the height of similar shapes, write a proportion of equal ratios.

Cross multiply to solve for y.

12y = 15(8)

12y = 120

y=10

b

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
