SOMEONE PLS HELP ME WITH THIS ASAP The diagram shows a circle with a
circunference of 88 cm and a sector of a circle.

Khairul uses the circle and the sector
to form a right cone with the height of 15 cm Calculate the volume, in cm of the cone formed.

Let's solve for the radius.

r = C / 2π = 88 / (2 * 22/7) = 14

Volume of a cone = 1/3 * πr²h

= 1/3 * 22/7 * 14² * 15

= 3080 cm³

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
