calculate the area (A) of the base of the cone. then, calculate the volume (V) of the cone. if necessary, round answer to the nearest hundredth.

Using 3.14 for pi

V = 66.99 cm^3

Using the pi button

V = 67.02 cm^3

Step-by-step explanation:

The area of the base of the cone is the area of a circle

A = pi r^2

A = pi * 4^2 = 16 pi

The volume of a cone is given by

V = 1/3 Bh  where B is the area of the base and h is the height

V = 1/3 (16 pi) * 4

V =64/3 pi cm^3

Using 3.14 for pi

V =66.9866666

Rounding to the nearest hundredth

V = 66.99 cm^3

Using the pi button

V =67.02064328

Rounding to the nearest hundredth

V = 67.02 cm^3

the answer to this question is 3/19

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
