Answer:
<h2>100πcm².</h2><h2>None of the options is correct</h2>
Step-by-step explanation:
Total surface area of a cone 
= 
Since the diagram is half of a cone, its surface area will be 
r = radius of the cone
l = slant height
From the diagram diameter of the cone = 16m;
r = 16/2 = 8m
l = 17m
Answer:
The annual increase in the percentage of a pollution can be determined by some mathematical calculation.
Step-by-step explanation:
- In order to determine the annual percentage increase over one year for a city population, we must do the following,
- First we must subtract starting value that is the initial population of the city at the starting of the year from the final value that is the final population of the city at the end of the year.
- Now divide the whole by the starting value.
- This gives you the value of increase in the rate of growth, Now inorder to obtain it in percentage format, we must multiply the resultant value by 100.
This finally gives you the rate of increase in the population in percentage.
Answer: 5 + 25n
Explanation: Let's simplify this problem using the distributive property.
In this problem, the 5 "distributes" through the parentheses which means that it multiplies by each of the terms inside.
So we have 5(1) + 5(5n) which simplifies to 5 + 25n.
Answer:
181.044m²
Step-by-step explanation:
First, work of the surface area of the base (bottom rectangle area)
Formula : base × height
6×2=12m²
Formula : LW+L
For the 8.8 bit i got 83.734 (sorry i can't be asked right now to put down all my working out)
and for the 9 i got 85.31
add them all together we get 181.044
