Question

A round table cover has 6 equal designs if the radius of the cover is the 28 cm . find the cost of the making design and the rate of .35 per cm ²

Answer 1

Radius(R) of the circular table is 28cm

Area of the circular table will be

πR square = (3.14)×(28)(28)

=2461.76 cm square

Since The round table has 6 equal designs and each costs 0.35 per cm square

therefore cost of 1 design will be

(2461.76)/(6×0.35)

= 1172.26666667 Will be the cost of making per design hope this helps :)

Answer 2

Answer:

Rs 162.66

Step-by-step explanation:

r = 28cm

Angle at centre = 360°

no. of divisions = 6

Angle at each sector = 360/6 = 60°

Area of each sector = 60/360 ×22/7 × 28 ×28

=1232/3

=410.66 cm²

Area of triangle = √3/4 (28)² =333 .2

Area of segment = 410.66-333.2

= 77.46 cm²

cost = rate×no.×area of each

= 0.35×6×76.46

= 162.66
