Answer:
Step-by-step explanation:
The formula to change a radical to rational (fractional) exponent is given below:
It means that the denominator of the fraction (in the rational exponent) goes OUTSIDE the root sign and the numerator goes as power to the number.
Using this, we can write as
Thus the rational exponent from is given by

1. A 210° sector of a circle of radius 10cm is used to make a cone. Find the radius of the base of the cone and it's height.
Answer: radius = 5.83 cm height = 8.12 cm
Step-by-step explanation:
First, let's find the circumference of the 210° section of the circle.
The circumference of the the cone is . We can use this to find the radius .
When you fold the 210° section into a cone, the slant height is the original radius of 10. We can use the radius and slant height of the cone to form a right triangle with the height. Use the Pythagorean Theorem to find the height.
radius² + height² = slant height²
which, in theory, would be the third side of the triangle formed by these three lines, would be 60 feet.
Answer:
no
Step-by-step explanation:
they are not similar -
the triangles angles are not congruent which then means that by AA criterion the triangles are not similar.
hope this helps!!
Answer:
Yes they are similar as the obtuse angle of 120 degree is the same and 2 other angles are acute and this example shows 4 degree range in difference. This would change the measure 0.4 only each side.
Similar is different to same, the exact meaning of similar is resemblance, the exact meaning is having a resemblance in appearance, character, or quantity, without being identical.
