Height (h) of cone = 9 cm
Let the radius of the cone be r.
Volume of the cone = 48\(\pi\) cm³
\(\frac{1}{3}\pi\)r²h = 48π cm³
r² =\(\frac{ 48 \ cm^3 × 3 }{ h}\)
r² = \(\frac{48\ cm^3 × 3 }{ 9\ cm}\)
r² = 16 cm²
r = \(\sqrt{16}\) cm²
r = 4 cm
Diameter of base d = 2 × radius(r)
= 2 × 4 cm
= 8 cm
A driver of a car travelling at \(52\) \(km \;h^{–1}\) applies the brakes Shade the area on the graph that represents the distance travelled by the car during the period.
Which part of the graph represents uniform motion of the car?
