What is the total surface area of this square pyramid?
slamgirl [31]

Answer:

The total surface area of this square pyramid is 297\ mm^{2}

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to

SA=b^{2} +4[\frac{1}{2}(b)(h)]

we have

b=9\ mm ----> the length side of the square base

h=12\ mm ----> the height of the triangular faces

substitute the values

SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}

36in rounded to the nearest tenth for circumference
WITCHER [35]

Answer: Remember that the tens place is two moves to the left of the decimal point (if it exists). To round to the nearest ten (nearest 10), we use the whole numbers place to determine whether the tens place rounds up or stays the same.

Solution steps:

Step 1: Locate and underline the tens place () and look to digit to the right (6):

36

Step 2: In this case, the digit to the right 6 is 5 or above. So, we add 1 to the tens place (). The digit(s) after the (6) are dropped. Thus, we get 40 as answer.

In short: 36 rounded to the nearest tens is 40.
