Answer: ( -6 , -6.5 )
Step-by-step explanation:
The formula for calculating Mid - point is given by
M = (
, 
)
= -5
= -7
= -9
= -4
substituting into the formula , we have
M = 
, 
M = 
, 
Therefore : mid point = ( -6 , -6.5 )
21 x 9 = 9 x 21 is the commutative property.
The area of a sphere: A = 4.π.R²
A= 5541.77 → 5541.77 = 4.π.R²
R² = (5541.77)/(4.π)
R² = 441; → R =√441; R = 21 cm
To find the surface area, use this square pyramid surface area formula: Square Pyramid Surface Area = 2 x B x S + B 2 B = Width of the Square Base S = Slant length of one of the triangular faces and is calculated from the height and base width by using the equation: S= The square root of [(.5B) 2 + Height 2] .
