The answer is 35 7/8. We know that to get the mean, you must add up all the numbers and divide by the amount of numbers. Set up the equation (36 3/4 +36 3/8+37 1/2+n)/4 = 36 5/8. After you solve for n, the missing number, you should get 35 7/8.

the diameter of a cylinder is 14cm.the height of the cylinder is 9cm. calculate the Volume and curved surface area

kicyunya [14]

Answer:

The volume is 1386 cm³ and curved surface area is 396 cm².

Step-by-step explanation:

Given that,

The diameter of a cylinder is 14 cm

Height of the cylinder is 9 cm

We need to find the volume and curved surface area .

If r is the radius, r = 14/2 = 7 cm

Volume of a cylinder is given by :

$V=\pi r^2 h\\\\V=\dfrac{22}{7}\times (7)^2 \times 9\\\\V=1386\ \text{cm}^3$

The curved surface area of the cylinder is given by :

$A=2\pi r h\\\\A=2\times \dfrac{22}{7}\times 7\times 9\\\\A=396\ \text{cm}^2$

So, the volume is 1386 cm³ and curved surface area is 396 cm².

A term life policy was offered to your spouse for $3.49 per $1,000.00. You want him to have $100,000.00 coverage, what is the pr

ruslelena [56]

Answer:

The premium is $349 per year

Step-by-step explanation:

We can easily solve this problem by applying a rule of three

$3.49 ---------------------------------------- $1000 coverage

x ---------------------------------------- $100,000 coverage

By using this relation, we can find how much money is needed to pay

x = ($100,000/$1000)*$3.49

x = (100)*$3.49

x = $349

The premium is $349 per year
