What is the volume of this cone

4096pi/3

Step-by-step explanation:

Volume is pi * r^2 * h/ 3

r (radius) = 16

h (height)= 16

pi * 256 * 16/3 = 4096pi/3

332°

Step-by-step explanation:

Given is an isosceles triangle,

Measures of base angles of an isosceles triangle are equal.

Therefore,

Measure of central angle

= 180° - ( 76° + 76°)

= 180° - 152°

= 28°

Measure of shaded angle

= 360° - 28°

= 332°
