Hey!

We know that d = 2r
where,
r - radius
d - diameter
Since it is given that d = 8 inches = 20.32 cm
Therefore,
radius ( r ) = d/2
= 8/2
= 4 inches = 10.16 cm //

It takes 3 tractors 2 hours to plow a square field whose side is 600 meters. find the number of hours it would take 5 tractors t
NeTakaya

Answer:

5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)

Step-by-step explanation:

Let's find out how much each tractor can plow each hour.

\frac{600^{2} }{3*2}=60,000m^{2} per tractor per hour

1,000^{2}=1,000,000m^{2} is the area of the field of side length 1,000 meters

5 tractors can plow 300,000m^{2} per hour.

\frac{1,000,000}{300,000}=3.33 hours

lisabon 2012 [21]

(Sorry if I'm wrong)



Enlarged means making it bigger, so you're making it 3 1/2 times bigger.

Try multiplying both the area and perimeter by 3.5

(6 x 3.5) (8 x 3.5)

P = 21cm and A = 28cm
