Question

- 2) Solve the following.
(6)
Which formula you will use to find the circumference of a circle when
length of a diameter is given?
) The measure of a central angle is 140°, then write the measure of its
corresponding minor arc.
i) Observe the figure alongside and write the
perimeter of the figure.

​

Answer 1

Answer:

$c = \pi \: d$

i) c. m = 140° (By Postulate 18, m + m = m is a semicircle, so m + 40° = 180°, or m = 140°.) d. m ∠ DOA = 140° (The measure of a central angle equals the measure of its corresponding minor arc.)

But where is the figure for 3rd question

Any way hope it helps you dear

Answer 2

Answer:

c = \pi \: dc=πd

i) c. m = 140° (By Postulate 18, m + m = m is a semicircle, so m + 40° = 180°, or m = 140°.) d. m ∠ DOA = 140° (The measure of a central angle equals the measure of its corresponding minor arc.

hi Mr saif how are you dear❤️
