Consider the solid S described below.
The base of S is an elliptical region with boundary curve 16X平方+25y平方 = 400. Cross-sections perpendicular to the x-axis are isosceles right triangles with hypotenuse in the base.
Find the volume V of this solid.
The base of S is an elliptical region with boundary curve 16X平方+25y平方 = 400. Cross-sections perpendicular to the x-axis are isosceles right triangles with hypotenuse in the base.
Find the volume V of this solid.
V＝4∫[0,5]（8-8x²/25）dx＝320/3.
（S⊿＝y²/2＝8-8x²/25）
