Step-by-step explanation:
Answer:
The volume and the curved surface area of the solid formed is
and
respectively.
Step-by-step explanation:
Given that,
A right triangle with sides 6 cm, 8 cm and 10 cm is revolved about the side 8 cm.
As the triangle is revolved at 8 cm it forms a cone of height 8 cm and radius 6cm.
Height, h = 8 cm
Radius, r = 6 cm
The volume of the solid formed is given by :
![V=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times \dfrac{22}{7}\times 8^2\times 8\\\\=301.71\ \text{cm}^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20h%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%208%5E2%5Ctimes%208%5C%5C%5C%5C%3D301.71%5C%20%5Ctext%7Bcm%7D%5E3)
The curved surface of the solid formed is :
![A=\pi rl](https://tex.z-dn.net/?f=A%3D%5Cpi%20rl)
l is slant height
![A=\pi r\times \sqrt{h^2+r^2} \\\\A=\dfrac{22}{7}\times 6\times \sqrt{8^2+6^2} \\\\=188.57\ \text{cm}^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5Ctimes%20%5Csqrt%7Bh%5E2%2Br%5E2%7D%20%5C%5C%5C%5CA%3D%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%206%5Ctimes%20%5Csqrt%7B8%5E2%2B6%5E2%7D%20%5C%5C%5C%5C%3D188.57%5C%20%5Ctext%7Bcm%7D%5E2)
Hence, the volume and the curved surface area of the solid formed is
and
respectively.
Answer:
270ft^2
Step-by-step explanation:
we need to multiply the terms given
15feet*18feet
we know feet*feet=![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
=ft^2
and
15*18=270
finally we have
270![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
=270ft^2
So your friend bought 1 set of brush and 5 bottles of paint
you bought 2 brushes and 7 bottles of paint
1 bottle=3.69
friends cost+your cost=51.69
total you bought 3 brushes and 12 bottles
each bottle is 3.69
12*3.69=44.28
totalcost=51.69=3brushes+12bottles
51.69=3brushes+44.28
minus 44.28 from both sides
7.41=3brushes
divide both sides by 3
2.47=1brush
1 set of paint brushes=$2.47
