perimeter = turn of the figure
P = 6 + 3 + 4 + 4 + 3 + 6 + 3 + 4 + 3 = 36
the triangle has 2 équal sides => isosceles
and 1 angle is 60° so the triangle is equilateral
Given:
Base area = 4π mm²
Height = 10 mm
To find:
The volume of the cylinder.
Solution:
Base of the cylinder is circle.
Area of the base = πr²
πr² = 4π
Volume of the cylinder = πr²h
Substitute 4π in place of πr².
= 4π × 10
= 40π mm³
The volume of the cylinder is 40π mm³.
Length of a carton :

Width of the carton :

Height of the carton :

Volume of the carton :
= Length × Width × Height



Therefore, the volume of the carton = 21.85 feet.
The answer is “A” hope I helped
