Answer:
189
Step-by-step explanation:
The pyramid has four triangular faces and a square base.
The area of a triangle is half its base times its height. The base of each triangle is 7, and the height of each triangle is 10. So the area of each triangle is A = ½ (7) (10) = 35.
The area of a square is the side length squared. The side of the square is 7. So the area of the square is A = (7)² = 49.
The total surface area is:
A = 4(35) + 49
A = 189
Answer:

Step-by-step explanation:
Given


Required
Determine the radius
Circumference (C) is calculated as:

Where r represents radius
Substitute values for C and 


Multiply through by 7/44





<em>Hence, the radius is 35cm</em>
Answer:
0.01
Step-by-step explanation:
Water is non viscous liquid and it has less density. The measure volume of water is 10.03 ml at 25 degree Celsius which is used to identify the standard deviation of the water.
Average volume of water 10.03ml.
Standard deviation is 0.0001 + 0.0001
Standard deviation is
= 0.01.
Mark can:
7*6=42
then just add back the 4 zeros
so its 42 0000
