Radius is 15 cm
Circumference = 2 pi r
C = 2 x 3.14 x 15cm
C = 94.2 cm
94.2 cm x 4 (revolutions) = 376.8 = D

Simplify 5/8×8 and explanation thanks.

Paha777 [63]

Explanation: Since 5/8 x 8 can be answered (because there is no variable), turn the whole number "8" into a fraction which would be: 8/1. Now, 5/8 x 8/1 equals 40/8 because 5 x 8 = 40 and 8 x 1 = 8. Now, simplify 40/8, which would be 20/4, simplifying it, even more, would be: 10/2, and one more time: 5/1 which is equivalent to 5. Hope this helps!
