Question

The area of an equilateral triangle is 49 square root 3 cm sq. Taking each angular point as centre, a circle is described with radius equal to half the length of the side triangle as shown in the figure. Find the area of the portion in the triangle not included in the circles.

Answer 1

Step-by-step explanation:

1/6×(7/2)^2×3= 1/6×49/4=49/24×3=6.125

49√3=84.87

therefore 84.70-6.125=you 78.745

Answer 2

Answer:

49 (root3-pi/2)

Step-by-step explanation:

3 sectors so

3×theta/360×pi×r^2

3×60/360×7×7×pi

3×1/6×49×pi

49/2×pi

total area is 49 root3

thus area not cveted by circles inside triangles is

49root3-49/2pi

49 (root3-pi/2)
