Work out the perimiter of a semi circle with radius of 3
Give your answer in term of pi

3pi + 6 units.

Step-by-step explanation:

The perimeter = the diameter + curved part.

Radius = 3 so the diameter = 2*3 = 6.

Length of the curved part = 1/2 * circumference of the circle = 1/2 * pi * diameter.

Perimeter = 6 + 1/2 pi * 6

= 3pi + 6 units.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
