For a birthday party, mrs. guilliano bought 11 spherical balloons, each with an inflated diameter of 1.5 ft.

what is the volume of helium needed to fill all 11 balloons?

select from the drop-down menu to correctly complete the statement.
the volume of helium needed to fill 11 balloons is about (1.8) (14.1) (19.4) (155.1) ft³

The volume of helium needed to fill 11 balloons is 19.4 ft³

C is correct

Step-by-step explanation:

For a birthday party, Mrs. Guilliano bought 11 spherical balloons, each with an inflated diameter of 1.5 ft.

Balloons are spherical with diameter 1.5 ft

Radius of spherical = Half of diameter

Radius (r) = 0.75 ft

Volume of each balloon ft³

Amount of helium for 1 balloon = 1.767 ft³

Amount of helium for 11 balloons = 11 x 1.767 = 19.4 ft³

Hence, The volume of helium needed to fill 11 balloons is 19.4 ft³

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
