Answer:
Here
Step-by-step explanation:
By converting the ratios to decimal numbers or percentages, you can compare them on a level field. Divide the numerator by the denominator of one ratio. For example, if the ratio is 4/7, then divide 4 by 7. This will yield a decimal number between zero and one.

Step-by-step explanation:
<u>Intervals in the Number Line</u>
When representing real intervals in the number line, we use solid lines that start from the lower or upper limit and end in the final number. If there is no limit, then we use an arrow pointing to plus or minus infinity.
If the endpoint is included in the interval, we place a filled circle, if it's not included, we use a hollow circle.
We want to show the interval
, this means we must include the 11 and go up to positive infinity. The only number line with such characteristics is that on the second option.

Answer:
Step-by-step explanation:
Remember, the formulas for the lateral surface area of a pyramid is 12pl and the total surface area is 12pl+B .
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder.
So, the formula for the lateral surface area of a right cone is L.S.A=πrl , where l is the slant height of the cone.
Find the lateral surface area of a right cone if the radius is 4 cm and the slant height is 5 cm.
L.S.A=π(4)(5)=20π≈62.82 cm2
