Question

A rectangular turf spread on the ground as shown in the figure find the radius of the stadium​

Answer 1

Answer:

50m is the answer

Step-by-step explanation:

Bu using Pythagoras theory we can find the diameter.

60² + 80 ² = 3600 + 6400 = 10000

Taking the square root we get, 100 cm as the diameter.

100/2 = 50m

Answer 2

Given :-

• Length of Rectangular turf = 80 m.
• Breadth = 60 m .

To Find :-

• The radius of the stadium is?

Solution :-

from image we can see that,

→ ABCD = Rectangle .

→ AB = DC = 60 m .

→ CB = 80 m.

→ ∠DCB = 90° . (Each angle of a rectangle is equal to 90°.)

then, in Right ∆DCB, we have,

→ DC² + CB² = BD²

→ 60² + 80² = BD²

→ BD² = 3600 + 6400

→ BD² = 10000

→ BD = √(10000)

→ BD = 100 m

so,

→ Radius of the stadium = BD/2 = 100/2 = 50 m (Ans.)
