Answer:

You have $10.600 Canadian dollars to spend.

Step-by-step explanation:

This problem can be solved by a rule of three.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

In this problem, we have the following measures:

-The number of US dollars

-The number of Canadian dollars.

As the number of US dollars increases, so does the number of Canadian dollars, which means that the relationship between the measures is direct.

The problem states that $1 US dollar is $1.06 Canadian dollars. The problme wants to know how much $10000 is in Canadian dollars. So:

1 - 1.06

10000 - x

x = 10000*1.06

x = $10.600

You have $10.600 Canadian dollars to spend.

Find the lateral area of a cylinder whose radius is 6 cm and height is 20 cm.
zaharov [31]
The surface area of a cylinder is define by the formula S.A.=2πrh+2<span>πr^2, where the first part of the formula refers to the lateral area, perimeter, or circumference and the second part to the area of the bases, which are circles.

On this exercise it is asked to find the lateral area of a cylinder whose radius is 6 cm, and has a height of 20cm. To find the lateral area of the cylinder you should substitute this values into the formula, S.A.=2</span>πrh, and as can be seen the answers are given in terms of <span>π or pi.

S.A.=2</span><span>πrh
S.A.=2</span><span>π(6cm)(20cm)
S.A.=2</span><span>π(120cm)
S.A.=240</span>π cm^2

The lateral area of the cylinder is 240
<span>π cm^2 or in other words letter B from the given choices.</span>
