The answer is b
If you plug those values on a graph it will show a straight line.
It would be 157. 05 08 4746 would be the total answer the remainder would be 157 or 3
In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
Step-by-step explanation:
A = pi × r²
A = pi × 13²
A = 530.93 km²
The formula for perimeter is length + length + width + width
You know that all the sides of a square are equal to each other. That means that all the values in the perimeter formula should be the same. Therefore you can divide 72 by 4 (perimeter divided by the number of sides)
72 / 4 = 18
^^^Each side is 18 in
The formula for are is...
A = length x width
so...
18 * 18 = 324
324 in^2
Hope this helped!
