Answer:
The perimeter of the rectangle is expressed as;
Step-by-step explanation:
Given;
area of the rectangle, A = 36 cm²
width of the rectangle, = W
Let L represent the length of the rectangle,
A = L x W
The perimeter of the rectangle is calculated as;
P = 2(L + W)
Substitute the value of L into the above equation;
Thus, the perimeter of the rectangle is expressed as
The formula for finding the surface area of a sphere is A=4π
. Since we already have the radius, we just plug that into the equation, like so:
A = 4 x 3.14 x
First, following the rules of PEMDAS, do the exponent, coming out with an answer of 1. Now, multiply 4 x 3.14, which is 12.56. 12.56 x 1 = 12.56.
Rounded to the nearest tenth, your answer is 12.6.
Hope this helps!
