Answer:

500 revolutions.

Step-by-step explanation:

The circumference of the wheel is 2 π r

= 2 *π  * 25.5

=  51π cm.

800 m = 80000 cm. so

Number of revolutions = 80000 / 51π

= 499.3.

So  to cover the 800 m the wheel must do at least 500 revolutions.

How do I do this problem??
Crank
Expanding 8x^3, we multiply 8*8 and x^3 by x^3 to get 64x^6. Since we know that the cube root of 64 is 4, we can separate that. Next, since you add exponents while multiplying, 6/3 is the exponent for the cube root of x^6=x^2. Therefore, your answer is 4x^2
