Here,
A sphere has 7cm radius
And it’s cut into tow half (2 hemispheres)
So, the radius of a hemisphere is also 7cm
Now,
TSA of hemisphere = 3 pie r^2
=3*22/7*7^2
=3*22/7*49
=3234/7
=462cm^2
Lastly,
The TSA of 2 hemispheres = 2* 462
=924cm^2
Hence,
The total surface area of the 2 hemisphere is 924cm^2
Without figure its not possible. What does this D come from? is it a triangle or quadrilateral or exterior angle? Furnish this information then only it can be solved.
<span>I guess, it is sum of 2 angles. If that is right, 2x + 5x = 91 or 7x =91 or x =13 so 2x = 26. Does that work? </span>
<span>Second is same type I guess! </span>
<span>2x-1 + 5x +2 = 57. So 7x = 56, x = 8. So DBC = 42. </span>
