Yogita Ingle 6 years, 9 months ago

The area of circle = 50.24 square metre
πr² = 50. 24
3.14 × r² = 50.24
r² = 50. 24 /3.14
r² = 16
r = 4
Diameter of circle = 2r = 2(4) = 8 meter
Circumference = 2πr = 2 (3.14) (4) = 25.12 meter

Rs57750

Gaurav Seth 6 years, 9 months ago

Length of the 1st cross road parallel to the length = 70 m
Breadth of the 1st cross road parallel to the length = 5 m

Area of the 1st cross road = 70*5

= 350 sq m

Length of the 2nd cross road parallel to the breadth = 45 m
Breadth of the 2nd cross road parallel to the breadth = 5 m

Area of the 2nd cross road = 45*5

= 225 sq m

Area of the common part of the 2 cross roads with width 5 m that lies at the center of the rectangular park = 5*5

= 25 sq m

Area of the 2 cross roads = Area of the 1st cross road + Area of the 2nd cross road - Common area

⇒ (350 + 225) - 25

⇒ 575 - 25

= 550 sq m

Cost of constructing the roads = Rs. 105 sq m

Total cost of constructing the road = 550*105

= Rs. 57750
