A polygon which 2 or more sides, if extended, cut inside the polygon. A polygon that both equilateral and equilateral (all sides and angles ). A quadrilateral whose opposite sides are parallel and equal. A 4-sides polygon whose legs (sides not parallel0 are equal. How many degrees are in the sum of the exterior of a polygon? The area of a trapezoid is 9 sq yd. Base 1 is 4 yd and Base 2 is 5 yd. Find the height. A = 1/2 h(b, + b2), A = 1/2 h(4 + 5), A = 1/2 h(9). Find the area of a triangle using Heron\'s Formula if side a is 1.4 m, side b is 1.2 m, and side c is 0.8 m. A squarroot 5(5 - a) (5 - b)(5 - c) 5 = 1/2 ( a,b,c) 5 =1/2 A baseplate in the shape of a parallelogram has one side = 46.76 cm and the other side (base) = 58.32cm. The total length of the base extended to include the end of the top side = 80.82 cm. Find the area of the plate. Round to 4 significant digits.
9) Inner diameter d1= 10cm.
Inner radius = d1/2 = 10/2 = 5cm.
Thickness of the pipe = 0.2cm.
Outer radius r2 = (5 + 0.2)cm = 5.2cm
Circumference of the outer pipe = 2 x pi x r2 = 2 x 3.14 x 5.2 = 32.656 cm.
