Answer:
As it is given that we have to use radius that's why we have to calculate radius first. Hence, the volume of the solid formed by right angle triangle is (251.42cm³).
hope it helps you Zara!

Answer:
Diameter = 8cm
Length = 17cm
Height = 15cm
We know that the volume of cube is
Where,
π = 22/7 or 3.14
r = radius
h = height
As it is given that we have to use radius that's why we have to calculate radius first.
We know that:-
where,
d = diameter
r = radius
=>(1/3) ×(22/7) ×4²×15
=>(1/3) ×(22/7) ×16×15
=>(22/7) ×16×5
=>251.428
Hence, the volume of the solid formed by right angle triangle is (251.42cm³).
Hope this helps :)
