A soup can that is a cylinder has a radius of 2x-1 and a height of 3x. What is the surface area of the soup can?

1 answer:

3 0

SA = ?
r = 2x - 1 
h = 3x 

Then, 

SA = 2π(2x - 1)² + 2π(2x - 1)(3x) 
==> 2π(4x² - 4x + 1) + 6πx(2x - 1) 
==> 8πx² - 8πx + 2π + 12πx² - 6πx 
==> 20πx² - 14πx + 2π units²

Option C is the correct values of the relationship between the number of cakes the baker makes and the number of bags of flour uses.

Solution:

Option A: Ratio of cakes baked to bags of flour used

$$\frac{9}{4}, \frac{18}{6}=\frac{3}{1} \text { and } \frac{27}{9}=\frac{3}{1}$

Here the ratios are not same.

So, this option is not true.

Option B: Ratio of cakes baked to bags of flour used

$$\frac{6}{2}=\frac{3}{1}, \frac{12}{4}=\frac{3}{1} \text { and } \frac{18}{6}=\frac{3}{1}$

Here the ratios are same.

So, this option is true.

Option C: Ratio of cakes baked to bags of flour used

$$\frac{4}{9}, \frac{6}{18}=\frac{1}{3} \text { and } \frac{9}{17}$

Here the ratios are not same.

So, this option is not true.

Option D: In this table cakes baked is 6 and the bags of flour is 18.

But a baker made 18 cakes using 6 bags of flour.

So, this option is not true.

Hence option C is the correct values of relationship between the number of cakes the baker makes and the number of bags of flour uses.
