Help! Please! What is the exact volume of the cone? 80π ft³ 4003π ft³ 400π ft³ 418710π ft³

400⅓ π ft³

Step-by-step explanation:

Data obtained from the question include:

Radius (r) = 5 ft

Height (h) = 16 ft

Volume (V) =..?

The volume of the cone can be obtained as follow:

V = ⅓πr²h

V = ⅓ × π × 5² × 16

V = ⅓ × π × 25 × 16

V = 400⅓ π ft³

Therefore, the volume of the cone is 400⅓ π ft³.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

.25
