185.04 mm

Step-by-step explanation:

The perimeter is 1/2 of the circumference plus the diameter

We need to go around the semicircle on the outside plus across the middle

1/2 C + d

1/2 2*pi * r  + 2r

pi *r +2r

3.14 (36)   + 2 (36)

113.04+72

185.04

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
