Answer:
139
Step-by-step explanation:
First we need to find diameter 132/3.14=42 rounded
Then we halve it to find radius 42/2=21
Formula for area is radius x radius x 3.14
21 x 21 = 441 x 3.14 = 138.74 round up is 139
Answer:
Option d - I and III.
Step-by-step explanation:
Given : If
and x and y are positive integers.
To find : Which of the following must be an integer?
Solution :
As we see all option there is a multiple of y.
So, we factoring the number 375
i.e. 


In order for 375y to be a perfect square,
The prime factorization of y must contain at least one 3 and one 5.
or y must be a multiple of 15.
If y is a multiple of 15, then
must be an integer.
and
must be an integer.
Therefore, I and III will be correct i.e. option d.
Answer:
1
Step-by-step explanation:
Gradient (slope) = change in y / change in x
(6-5) / (3-2) = 1/1 = 1
The gradient is 1
