Answer: Capacity = 70.227 Cube cm ( Approx )
Total Surface area = 109.9 square cm
Step-by-step explanation:
Since the volume of a cone,
![V = \frac{1}{3} \pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20r%5E2h)
Where r is the radius of the cone,
h is the height of the cone,
Here, radius, r = 3.5 cm
Height, ![h = \sqrt{6.5^2-3.5^2} =5.47722557505](https://tex.z-dn.net/?f=h%20%3D%20%5Csqrt%7B6.5%5E2-3.5%5E2%7D%20%3D5.47722557505)
Thus, the volume of the cone,
![V = \frac{1}{3} \pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20r%5E2h)
![=\frac{1}{3} \times 3.14\times (3.5)^2\times 5.47722557505=70.2271605815\approx 70.227\text{ cube cm}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%203.14%5Ctimes%20%283.5%29%5E2%5Ctimes%205.47722557505%3D70.2271605815%5Capprox%2070.227%5Ctext%7B%20cube%20cm%7D%20)
And, Total surface area,
![A = \pi r l+\pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%20l%2B%5Cpi%20r%5E2)
Where l is the slant height of the cone,
Here, l = 6.5 cm
Thus, the curved surface area of the given cone,
![A = 3.14\times 3.5\times 6.5 + 3.14\times (3.5)^2= 71.435+38.465=109.9\text{ square cm}](https://tex.z-dn.net/?f=A%20%3D%203.14%5Ctimes%203.5%5Ctimes%206.5%20%2B%203.14%5Ctimes%20%283.5%29%5E2%3D%2071.435%2B38.465%3D109.9%5Ctext%7B%20square%20cm%7D)
Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
To be a function every x should have only one y-value.
<span>a. (0,0), (1,1), (2,2), (3,3), (4,4) - We do not see repeating values of x, so it is a function
</span>b. (0,8), (1,6), (2,4), (3,2), (4,0)- We do not see repeating values of x, so it is a function
<span>c. (3,0), (3,1), (3,2), (3,3), (3,4) - We see repeating value of x, that means that one value of x corresponds many values of y , so it is not a function.</span>
