Question

IF U = π(r + h), find r when U = 165 and
h = 11/4. ​

Answer 1

Answer:

Step-by-step explanation:

U = π(r+h)

Here

U=165

H = 11)4

Find r

165 = 22/7( r+ 11/4)

r+ 11/4 =165×7/22

r+ 11/4 = 52.5

r = 52.5+2.75

r =55.25

Answer 2

Given:

U= π(r+h)

U=165

h= 11/4

To find:

r = ?

Solution:

U= π(r+h)

165= 22/7 (r+11/4)

r + 11/4 = $165* \frac{7}{22}$

r + 11/4 =1155/22

r + 11/4 = 52.5

r + 2.75= 52.5

r = 52.5 - 2.75

r = 49.75
