paper cups at a water cooler have the approximate shape of a cone with a diameter of 8 cm and a height of 9.5 cm

what is the best approximation for the volume of the paper cup?

79.6 cm³

159.2 cm³

477.5 cm³

636.7 cm³

Step-by-step explanation:

The volume of cone is given by :-

Given: The diameter of paper cups = 8 cm

Thus, the radius of paper cup (r)=

The height of paper cup (h)= 9.5 cm

Now, the volume of paper cup will be :-

Hence, the  best approximation for the volume of the paper cup

78.59 is the mean

step-by-step explanation:

(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
