A circular flower bed is 23m in diameter and has a circular sidewalk around it that is 3m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi.

given the diameter of the circular flower bed is 23m.

therefore radius of the flower bed=23/2

=11.5m

area of the flower bed=πr²

=3.14×10×10

=314m²

if the path is all around the flower bed and it's width is 3m, then the radius of the flower bed along with the path will be = 10+3

=13m

therefore it's area=πr²

=3.14×13×13

= 530.66m²

x = 12

y = 15

step-by-step explanation:

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
