Question

The yield of wheat in the first and second field is given by the diagram
below:
The first field has radius 8 cm and second field has radius 10 cm. If the first
field yields 800 kg of wheat then the yield of second field is?
(A) 1250 kg
(B) 775 kg
(C) 900 kg
(D) 1042 kg
(E) None of these

Answer 1

Answer:

c) 900kg

Step-by-step explanation:

second field is 900 kg

Answer 2

Answer:

(A) 1250 kg

Step-by-step explanation:

Area of first field = πr^2

= 3.14×8×8

= 200.96 cm

Area of second field = 3.14×10×10

= 314 CM

If area of 200.96 can produce 800 kg then how much can an area of 314 produce?

800/200.96 = x/314

= 1250 kg
