Answer:

an = 7.5 - 5.5(n - 1).

Step-by-step explanation:

The common difference d = -5.5.

The first term is given as 7.5.

an = a1 + (n - 1)d

= 7.5 + (n - 1)-5.5

= 7.5 - 5.5(n - 1)

Nat2105 [25]
= -3/2 * -5 1/4
convert 5 1/4 to improper fraction

Acone has a height of 7 ft and a radius of 4 ft. Which equation can find the volume of the cone?
Marina86 [1]

Answer:

Volume of the cone = 117.06\,feet^3

Step-by-step explanation:

Height of the cone = 7\,feet

Radius of the cone = 4\,feet

Volume of a cone is:

              \pi \times r^2\times \dfrac{h}{3}

As, \pi =\dfrac{22}{7} =3.14

Volume is:      

                 =3.14\times(4\times 4)\times \dfrac{7}{3}\\\\ =3.14\times 16 \times 2.33\\\\=3.14\times 37.28\\\\=117.06\,feet^3

The volume of the cone is: 117.06\,feet^3
