Distance covered in 1 rotation = circumference of the wheel
= 2r
= 2 x x 14
= 2 x 22 x 2
= 88 inches
Distance covered in 10 rotations = 88 x 10 = 880 inches
Therefore, the bike covers 880 inches after 10 rotations.
Answer:
x = 6 m
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here A = 60, h = 8, a = 9 and b = x , thus
× 8 × (9 + x) = 60, that is
4(9 + x) = 60 ( divide both sides by 4 )
9 + x = 15 ( subtract 9 from both sides )
x = 6 m
