Answer:
A) The maximum error in the calculated surface area: 
Relative error: 
B) The maximum error in the calculated volume: 
Relative error: 
Step-by-step explanation:
A) The formula for the surface area is:

The measured value is the circumference which is equal to:

then the radius is:

Substituting in the formula of the surface:

Using the formula to calculate the error:

Where
is the variable measured and
is a function of
(
).

We have C=80cm and dC=0.5cm

The relative error is the maximum error divide by the total area. The total area is: 

B) The formula for the volume is:

Using 

The maximum error is:

The calculated volume is:

The relative error is:


- Cricket = 55%
- Football = 30%
- Other games = Remaining (?)
So, the percent of people who like <u>other games</u> equals:
= 100 – (55 + 30)
= 100 – 85
= 15%
<u>If </u><u>the </u><u>total </u><u>no.</u><u> </u><u>of.</u><u> </u><u>people</u><u> </u><u>is </u><u>6</u><u>0</u><u>,</u><u>0</u><u>0</u><u>,</u><u>0</u><u>0</u><u>0</u>:
★ Cricket
= 60,00,000 × 55/100
= 33,00,000
★ Football
= 60,00,000 × 30/100
= 18,00,000
★ Other sports
= 60,00,000 × 15/100
= 9,00,000
Answer:
<h2>1</h2>
Step-by-step explanation:
Use the Pythagorean theorem:

We have

Substitute:

<em>subtract 9 from both sides</em>
