Can someone show me the steps to solve #83 please?

gulaghasi [49]

Answer:

18π ≈ 56.5 meters

Step-by-step explanation:

The length of the arc of a circle is given by the formula ...

s = rθ . . . . where r is the radius, and θ is the central angle in radians

<h3>Application</h3>

You are given the values of r and θ, so you only need to put them into the formula and simplify.

s = (27 m)(2π/3) = 18π m

The length of the arc is 18π meters, about 56.5 meters.

Mrs. Adams deposited $12,000 into an account that earns an annual simple interest rate of 3.25%. She makes no other deposits or

lisabon 2012 [21]

Answer:

<em>Mrs. Adams will earn $3,120 of interest at the end of year 8.</em>

Step-by-step explanation:

<u>Simple Interest</u>

In simple interest, the money earns interest at a fixed rate, assuming no new money is coming in or out of the account.

We can calculate the interests earned by an investment of value A in a period of time t, at an interest rate r with the formula:

$I=A.r.t$

Mrs. Adams deposited an amount of A=$12,000 into an account that earns an annual simple interest rate of r=3.25%. We must find the interest earned in t=8 years. The interest rate is converted to decimal as:

$r=3.25/100=0.0325$

The interest is then calculated:

$I=12,000\cdot 0.0325\cdot 8=3,120$

Mrs. Adams will earn $3,120 of interest at the end of year 8.

What is the surface area of the cylinder express the answer in terms of Pie. D=8cm h=18cm A: 152 B:176 C:304 D:792

yaroslaw [1]

Answer:

Step-by-step explanation:

D = 8 cm

r = 8/2 = 4 cm

h = 18 cm

Surface area = 2πr(h + r)

=2*π * 4 * ( 4 + 18)

= 2*π*4*22

=176π cm²
