Question

The area of curvature of a solid is equal to the area of curvature of a solid elliptical tube. The height and diameter of the funnel are both 12 cm then find the length of the radius.
Please solve..​

Answer 1

Answer:

$\huge{\boxed{\rm{\red{Radius=6cm}}}}$

Step-by-step explanation:

Given:-

The area of curvature of a solid is equal to the area of curvature of a solid elliptical tube. The height and diameter of the funnel are both

12 cm

To find:-

find the length of the radius.

Solution:-

The area of Curvature of the solid galaxy

=>surface area of a sphere=4πr²

Curved surface area of a solid elliptical tube

=>Curved surface area of the Cylinder

=>2πRh sq.units

Here areas of two solids are equal

height=diameter=12 cm

=>h=2R=12cm

=>R=6cm

=>4πr²=2πRh

=>2r²=Rh

=>2r2=6×12

=>2r²=72

=>r²=72/2

=>r²=36

=>r=±6cm

r can not be negative

r=6cm

Answer:-

The length of the radius=6cm

Answer 2

Answer:

Answer:

\huge{\boxed{\rm{\red{Radius=6cm}}}}
