Answer:
x=13.6
Step-by-step explanation:
First, let's distribute.
7x-21=4x+20
Second, let's subtract 4x from both sides.
3x-21=20
Next, let's add 21 to both sides.
3x=41
Lastly, let's divide 3 from both sides.
x=13.66666667
x=13.6
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
Add
should be
5^n = 5^14
then
n = 14
