Question

find the perimeter of semicircle plate of radius 3.5 CM​

Answer 1

Answer:

The perimeter of the semicircle is 18 cm

Step-by-step explanation:

• Perimeter is the distance around a 2Dshape.
• it is the length of the boundary of any shape.

• The perimeter of the semicircle is given by $P=\pi r+2r$

         where r is the radius of the semicircle.

Step 1 of 1:

• The radius of the semicircle is 3.5 cm.
• The perimeter of the semicircle is given by

         $P=\pi r+2r$

          $P=\frac{22}{7}*3.5+2*3.5\\P=22*0.5+7\\P=11+7\\P=18 cm$

• Therefore, The perimeter of the semicircle is 18 cm.
