The top of the cylindrical can shown below has a diameter of 7 centimeters (cm) What is the circumference, in centimeters, of the top of the can? Round your answer to the nearest hundredth of a centimeter. Use 3.14 for pi

A: 10.99

B: 21.99

C: 38.47

D: 43.96

B: 21.99

Step-by-step explanation:

recall that for a circle, circumference is given by:

circumference = 2π x radius

= π x diameter

we are given taht the diameter is 7 cm and π = 3.14

simply substitute these values into the formula for circumference:

circumference

= π x diameter

= 3.14 x 7

= 21.98

(the closest answer to this is B: 21.99)

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
