Given:

The diameter of the wheel is 2 feet.

Number of revolution = 100

To find:

The total distance covered by the bicycle.

Solution:

The circumference of a circle is:

C=2\pi r

Where, r is the radius of the circle.

The diameter of the wheel is 2 feet. So, the radius of the circle is 1 feet.

Putting \pi =3.14, r=1 in the above formula, we get

C=2(3.14)(1)

C=6.28

It means the distance covered by the wheel in one revolution is 6.28 feet.

Number of revolution is 100. So, the total distance covered by the wheel in 100 revolution is:

6.28\times 100=628

The total distance covered by the bicycle in 100 revolution is 628 feet.

Therefore, the correct option is B.

Katena32 [7]

Answer: When we add or subtract rational numbers that have the same denominator, we add or subtract only the numerators. The denominators stay the same. When we add or subtract rational numbers with unlike denominators, we need to change the rational numbers to equivalent rational numbers that have the same denominators, before we find the sum or difference.

Gail is making costumes for a school play. Each rabbit costume needs one and one half yards of white fur fabric, a yard of blue
olga nikolaevna [1]

Answer:

Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.

Step-by-step explanation:

We are given that,

The amount of yards for making one costume of different fabrics are,

White fur fabric = 1\frac{1}{2} = \frac{3}{2} yards

Blue striped fabric = 1 yard

Pink felt for ears = \frac{1}{4} yards.

So, we have,

The amount required to make 8 costumes are,

White fur fabric = \frac{3}{2}\times 8 = 3×4 = 12 yards

Blue striped fabric = 1×8 = 8 yards

Pink felt for ears = \frac{1}{4}\times 8 = 2 yards.

Thus, Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.
