The answer is 32/9 , or 1.68.
Consider one pyramid
Side length of base = 1.5cm and its height is 1 cm
Slant height of one of the lateral faces = sqrt(1^2 + 0.75^2) = 1.25 cm
Area of one of the triangular faces = 0.5 * 1.5* 1.25 = 0.9375 cm^2
There are 8 of these so the required surface area = 8 * 0.9375
= 7.5 cm^2 Answer

3 is equal to 3 which can be it and 2 is less than 3
the answe is ....
.....
-6,1
step by step
first you sympypfly the answer and then what you want to do is mutyplying te answer by the formula of the graph by then you should already have the table of the formula,then what you want to do is to try to coordinate the number of the graph,AND THA'S HOW YOU GET (-6,1)
Answer:
Step-by-step explanation:
The circumference of a circle can be found using the following formula:
where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.
The radius is 15 feet.
Multiply.
Now we know the diameter. Substitute 30 feet in for d.
We are using 3.14 for pi, so substitute it in.
Multiply.
The circumference of the circle is 94.2 feet.
