Sybil and her 3 friends will receive ¹/₈ pizza
<h3>Further explanation</h3>Order of Operations in Mathematics follow this following rule :
This rule is known as the PEMDAS method.
In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.
Let us tackle the problem !
Let :
<em>Initial Amount of Pizza = X</em>
Sybil has 1/2 pizza left over →
<em>She wants to share the pizza with her 3 friends.</em>
We will divide the remaining pizza into 4 parts.

Answer:
Step-by-step explanation:
Surface area = lateral area + 2(area of base)
Lateral area = perimeter of base * height.
Because it is a isosceles right triangle, both sides are equal.
= 72
2 = 72. Divide both sides by 2
= 36. Square both sides.
x = 6.
So the perimeter of the base = 6 + 6 + = 20.485281374239
Lateral area = 20.485281374239 * 7 = 143.397
Area of base is (1/2)base * height.
(1/2)(6)(6) = 18
Using the surface area formula
surface area = 143.397 + 2(18) = 179.4
