added we always get a negative integer and q: when two negative integers are added, we get a positive integer, then.

A: Both p and q are true

B: p is true and q is false

C: p is false and q is true

D: Both p and q are false

Solution:

Explanation:

Let, two integers 8 (Positive integer) and -2(negative integer)

Sum of 8 and -2 is 6 (positive integer)

Which implies that, It is not necessary “when a positive integer and a negative integer are added we always get a negative integer ” It can be positive also.

P statement is false

Let two negative integers be -2 and -3

The sum of -2 and -3 is -5 which is negative.

It contradicts the q statement.

q statement is false.

Final Answer:

Option (D) is correct. As, both the statements are false.

Use =3.14 .

Solution:

Explanation:

Given, 

The radius of a circle r = 15cm

Circumference of a circle = 2r

=2×3.14×15

= 94.2cm 

Final Answer:

Hence, the circumference of a circle whose radius is equal to 15cm is 94.2cm.
