valina [46]3 years ago
3 0

General formula of the circle

(x-a)² + (y - b)² = r²,


where (a,b) - coordinates of the center, r - radius of the circle.


(x-3)²+(y+4)²=4

(x-3)²+(y+4)²=2²


So, the center is (3, -4) and radius r = 2.


A. (3, –4); 2

Find the surface area. round to the nearest hundredth when necessary.
Dmitry_Shevchenko [17]

Answer:

The surface area of the cuboid is 648 m^2

Step-by-step explanation:

What we have here is cuboidal in outlook

By using the formula for the surface area of a cuboid, we can get the surface area of the shape

mathematically, we have the surface area of a cuboid as follows;

2(lb + lh + bh)

where l is the length, b is the breadth (width) and h is the height

We can have the length as 9 m, the width as 9 m and the height as 13.5 m

Substituting these values, we have the surface area of the cuboid as;

A = 2(9(9) + 9(13.5) + 9(13.5))

A = 2(81 + 243)

A= 2(324)

A = 648 m^2
