Before the celebration for
Groundhog Day, the city
set up an octagonal
barrier around the park. If
each side of the barrier
was 145 2/3 yards long,
how many feet of fencing
were used to create the
barrier2

Solution:

8-sided shape is called an octagon

The city  set up an octagonal  barrier around the park

Each side of the barrier  was 145 2/3 yards long

Convert yards to feet

1 yard = 3 foot

Therefore,

How many feet of fencing  were used to create the  barrier

1 side = 437 foot

8 sides = 8 x 437 = 3496 feet

Thus 3496 feet of fencing were used to create the barrier

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

b
