<h3>What is a semicircle?</h3>
A semicircle is a part of a circle cut through its diameter.
Analysis:
perimeter of a semicircle = πr
where r = 6/2 = 3mm
perimeter of a semicircle = π(3) = 3π
perimeter of incomplete rectangle = L+2B, L = 6mm, B = 3mm
perimeter of rectangle = 6mm +2 x 3= 12mm
perimeter of shape = (3π+12)mm
In conclusion, the perimeter of the rectangle is (3π+12)mm

Answer:
Red and Green are parallel
Black and Blue are perpendicular
Step-by-step explanation:
Parallel lines need to have the same slope. Lines red and green both have a slope of 1/2.
The slopes of two lines that are perpendicular have to be opposite reciprocals, and must be multiplied together to get -1. Line black has a slope of -4, and line blue has a slope of 1/4. Both of them multiplied together equals -1.

Answer:
The number of original students desk were there before the purchase is 980 .
Step-by-step explanation:
Given as :
The total number of students and teachers new desks to be purchased = 295
The number of teacher's new desk to be purchased = 50
So , The number of student's new desk to be purchased = 295 - 50 = 245
The number of student's new desk to be replaced this year = 
of the original students desk
Let The number of original students desk were there before the purchase = x
Or, According to question
of x = 245
Or, x = 245 × 4
∴ x = 980
Hence The number of original students desk were there before the purchase is 980 . Answer
