Step-by-step explanation:
the formulae to find the perimeter of a rectangle is p = 2(l+w)
<em>where</em>
p= perimeter
L = length
W = width
just add the length and width {given in the question} , and multiply them by 2
answer: = 2(11+4)
= 2 × 15
= 30 m

Answer:
Gregoire is correct; the diameter is a chord that passes through the center of the sphere.
Step-by-step explanation:
A sphere is a geometrical shape formed from a circle. Some of its parts are: diameter, center, radius circumference, etc.
The center of a sphere is a point at its middle. The diameter is a straight line, e.g a chord, that is drawn from one point on the circumference of a sphere to another point and passes through its center. While radius is a line that is from the center of the sphere to a point on its circumference.
A diameter is twice of a radius, so that:
Radius = 
⇒ Diameter = 2 × Radius
Therefore with respect to the question, Gregoire is correct because a diameter is a chord that passes through the center of the sphere.
