Hello,
Yes since (2*6.4)²+9.6²=256=16²
Angle A=90°
Answer:
2 l think
Step-by-step explanation:
The formula for surface area of a sphere is A=4*PI*r^2
Using that formula and the known surface are we can find the radius. We can then use that to find the volume.
500 = 4*PI*r^2
Divide both sides by 4:
500/4 = PI *r^2
125 = PI *r^2
Divide both sides by PI
125/PI = r^2
39.79 = r^2
r = SQRT(39.79)
r = 6.3 cm
Now we can find volume using V=4/3*PI*r^3
V = 4/3 *PI *6.3^3
V= 1051.3
The answer is C

Answer:
Question no 2: shape 1 = 4x180=720 / shape 2= 720/6=120
Step-by-step explanation:
Shape 1 :
The reason we multiply 4 by 180 is because the sum of interior angles of a triangle sum up to 180 and there are 4 triangles so you multiply 4x180 to get 720.
Shape 2 :
In a hexagon all the sides are of the same length (congruent) and all the interior angles are all the same size (congruent) So the find the measure of the interior angles we know that the sum is 720 and there are six angles so... we divide 720/6 which gives us 120
