Answer:
The length of the arc is 1.6 cm
Step-by-step explanation:
To find the value of the length of the arc, we use the length of arc formula
Mathematically, this is;
theta/360 * 2 * pi * r
where theta is the central angle
In this case pi/4 = 180/4 = 45 degrees
r = 2 cm
So the measure of the length of the arc will be;
L = 45/360 * 2 * 22/7 * 2
= 1/8 * 4 * 22/7
= 22/7 * 1/2 = 11/7 = 1.57 cm which is approximately 1.6 cm
Because the absolute value of something can't be a negative number, there is no solution.
Answer:
117
Step-by-step explanation:
Subtract from 180 to get interior and exterior angles.
180 - 101 = 79
79 + 38 = 117
180 - 117 = 63
180 - 63 = 117
Answer: 745
Step-by-step explanation: if there were initialy 80 books and its increasing by 25% every month, for month 1 we have:
25% = 0,25
increase is 1+0.25
M1 = 80.(1+0.25)¹ = 80.1.25 = 100
M10 = 80 (1+0.25)¹⁰ = 80. 9.313225 = 745.05 (end of the month)
Similar figures are figures of the same shape but different (or same) size.
Thus, they look the same, but one is bigger than the other by a scale factor.
Congruent figures are figures of the same shape AND same size.
They can be mapped onto each other using any type of transformation (besides dilations).
Similar figures can be dilated.
