Answer:

The square cake has a larger area

Step-by-step explanation:

Square cake

Area = L*L = (9inch*9inch) = 81 inch^2

Round cake

(8 inches corresponds to the diameter, so the radius is 4 inches)

Area  = pi*(radius^2) = 3.1416*(8inch/2)^2 = 50.265 inch^2


Since   81 inch^2 > 50.265 inch^2

The Square cake has a bigger area

vladimir1956 [14]

Answer

Find out the  how far into the country does he go.  

To proof

Let us assume that the total diatance travelled into the country be x .

Formula

Time =\frac{Distance}{Speed}

As given

A cyclist rides into the country at an average speed of 10 miles per hour. When his bicycle gets a flat tire,

he walks it back at an average speed of 3 miles per hour.

If he returns home 6 and a half hours after he starts i.e the total time including the bike time and walk time of the cyclist be 6.5 hours.

Than the equation becomes

\frac{x}{10} +\frac{x}{3} = 6.5

L.C.M of (10,3) = 30

Than the equation becomes

3x +10x = 195

solving

13x = 195

x = \frac{195}{13}

x = 15 miles into the country

Hence proved
