Answer: the answer is that is decreases 25 %
Step-by-step explanation:
Let
p---------------> is the perimeter of the base
s--------------> is the slant height
ba-----------> is the area of the base
la-----------> is the lateral area
we know that
[surface area of the pyramid]=area of the base+perimeter of the base*slant height/2
so
[surface area of the pyramid]=ba+p*s/2
la=p*s/2
[surface area of the pyramid]=ba+la
the answer is
surface area=ba+p*s/2
surface area=ba+la
Answer:
minimum is -3,0
Step-by-step explanation:
The equation of a circle that contains the point (–5, -3) and has a center at (-2, 1) is (x + 2)² + (y - 1)² = 25
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The circle contains the point (–5, -3) and has a center at (-2, 1), hence:
![radius=\sqrt{(1-(-3))^2+(-2-(-5))^2}=5\ units](https://tex.z-dn.net/?f=radius%3D%5Csqrt%7B%281-%28-3%29%29%5E2%2B%28-2-%28-5%29%29%5E2%7D%3D5%5C%20units)
The equation is:
(x - (-2))² + (y - 1)² = 5²
(x + 2)² + (y - 1)² = 25
The equation of a circle that contains the point (–5, -3) and has a center at (-2, 1) is (x + 2)² + (y - 1)² = 25
