Question

the difference between curved surface area and total surface area of cone is 49π cm². the radius of base of cone is
​

Answer 1

Answer:

radius = 7 cm

Step-by-step explanation:

Total surface Area = area of flat surface + area of curved surface

area of flat surface = Total surface Area - area of curved surface

area of flat surface = 49$\pi$

$\pi * r^{2}$ = 49 * $\pi$

$r^{2}$ = 49

r = 7
