Answer: Surface area is equal to 200
Volume is equal to 333.33
Step-by-step explanation:
First, let's do surface area.
The surface area of a pyramid is equal to 1/2(perimeter of base)(lateral height) + area of the base
The perimeter of the base is 10(4) = 40; as the base is a square with a side length of 10.
The lateral height is given as 5 cm.
The area of the base is 10(10) = 100.
We can plug those numbers into the equation to get 1/2(40)(5) + 100, which comes out to be 200
.
Now for volume.
The volume of a pyramid is equal to 1/3(area of the base)(height).
We already have the area of the base, which is 100.
The height is given as 10 cm.
Plugging those numbers into the equation, we get 1/3(100)(10), which is 1000/3 or about 333.33
.
Hope this helps!
Answer:
= - 3
Step-by-step explanation:
Note the common ratio r between consecutive terms, that is
r = - 18 ÷ - 3 = - 108 ÷ - 18 = 6
This indicates the sequence is geometric with n th term ( explicit formula )
= a
where a is the first term and r the common ratio
Here a = - 3 and r = 6, thus
= - 3
36a+16b. The greatest common factor is 4
= 4(9a+4b)
