Answer:
7
Step-by-step explanation:
formula for circumference of a circle is d
7 = d
d = 7
The first working out is correct, z = 3
6. the answer is 6. because 3x what she has is equal to 18 all u do is divide. u get six.
The length of an arc subtended by a central angle is proportional to the circle's circumference. If the given central angle has measure and the circle has radius , then the arc has length such that
where is given in radians. Then
If is given in degrees, then
If the triangles are similar, then the corresponding ratio of their sides have equal ratios. Through ratio and proportion, we would determine the answer.
5/6 = x/9, where x is the length for side PN
Transposing the equation so that x is on the left side:
x = (5/6)*9
x = 7.5
