<span>Consider the solid s described below. the base of s is the region enclosed by the parabola y = 5 - 5x2 and the x-axis. cross-sections perpendicular to the x-axis are isosceles triangles with height equal to the base. find the volume v of this solid.</span>
Answer:
37.699 cm³
Step-by-step explanation:
Sa of cone:
pi×r×l + pi×r²
(3pi × l) + (pi × 3²) = 24pi
3l + 9 = 24
3l = 15
l = 5 (slant height)
Height: h
h² + r² = l²
h² + 3² = 5²
h² = 16
h = 4 cm
Volume = ⅓ × pi × r² × h
= ⅓ × pi × 3² × 4
= 12pi cm³
= 37.69911184 cm³
Well, not specific. But after 7 hour the bus will be 210mi away
