The image showing the dimensions is missing, so i have attached it.
Answer:
A = 156 square feet
Step-by-step explanation:
To find how much plywood Jesse will need to cover all the surface simply means we are to find the surface area.
The surface area of the triangular prism is given by;
A = (2 * (Area of the base)) + (Perimeter of base x height)
Now, area of the base=bh/2
b = 3 ft
h = 4 ft
area of the base = 3*4/2 = 6 ft²
perimeter of the base = L + b + h = 4 + 3 + 5 = 12 ft
height of the prism;h = 12 ft
Thus;
surface area of the triangular prism;
A = (2 * 6) + (12*12)
A = 12 + 144
A = 156 ft²
(1) let "r" denote number of rabbits, "c" number of chickens

Answer:
5.73cm
Step-by-step explanation:
Given parameters:
Circumference of the circle = 36cm
Unknown
Length of the radius = ?
Lets represent the radius by r
Solution
The circumference of a circle is the defined as the perimeter of a circle. The formula is given as:
Circumference of a circle = 2πr
Since the unknown is r, we make it the subject of the formula:
r =
r = =
= 5.73cm
