<h2>90 sq in</h2>
Step-by-step explanation:
The total area in the figure can be divided into two areas.
The
is the area of the
rectangle.
The
is the area of the adjacent triangle to the rectangle.
![area_{rectangle}=length\times breath=10\times 8=80](https://tex.z-dn.net/?f=area_%7Brectangle%7D%3Dlength%5Ctimes%20breath%3D10%5Ctimes%208%3D80)
![area_{triangle}=\frac{1}{2}\times base \times height=\frac{1}{2}\times 4\times 5=10](https://tex.z-dn.net/?f=area_%7Btriangle%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20base%20%5Ctimes%20height%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%204%5Ctimes%205%3D10)
Total area=
90
By definition, the volume of a cone is given by:
v = (pi * r ^ 2 * h) / 3
Where,
r: radius
h: height
Clearing the radio we have:
r = root ((3 * v) / (pi * h))
Substituting values:
r = root ((3 * (256)) / (3.14 * (16)))
r = 3.91 cm
Answer:
The radius of the cone is:
r = 3.91 cm

Answer:
Step-by-step explanation:
The formula for the area of a circle is A=πr²
r=6cm in this case
Given:
12cm to 2.5mm
To find:
The simplified for of given statement.
Solution:
We know that,
1 cm = 10 mm
12 cm =120mm
We have,
12cm to 2.5mm
It can be written as
![\dfrac{12\ cm}{2.5\ mm}=\dfrac{120\ mm}{2.5 mm}](https://tex.z-dn.net/?f=%5Cdfrac%7B12%5C%20cm%7D%7B2.5%5C%20mm%7D%3D%5Cdfrac%7B120%5C%20mm%7D%7B2.5%20mm%7D)
![\dfrac{12\ cm}{2.5\ mm}=\dfrac{120}{2.5}](https://tex.z-dn.net/?f=%5Cdfrac%7B12%5C%20cm%7D%7B2.5%5C%20mm%7D%3D%5Cdfrac%7B120%7D%7B2.5%7D)
![\dfrac{12\ cm}{2.5\ mm}=48](https://tex.z-dn.net/?f=%5Cdfrac%7B12%5C%20cm%7D%7B2.5%5C%20mm%7D%3D48)
Therefore, the value of 12 cm to 2.5 mm is 48 or 48:1.
