Answer:
504
Step-by-step explanation:
area of the square -> 14*14 = 196
area of one of the triangles -> 1/2(11*14) = 77
area of all four triangles -> 77 * 4 = 308
surface area = area of square + area of four triangles
= 196 + 308
= 504

The surface area of a sphere is A = 4 π R² .
Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.
Circumference = π (diameter)
Divide each side by π : Diameter = circumference / π
Radius = 1/2 diameter: Radius = circumference / (2 π)
Area = 4 π R² =
4 π (circumference/2π)² =
4 π (circumference)² / 4 π²
Divide top and bottom by 4π : Area = (Circumference)² / π
Circumference = 37.68 units
Area = (37.68)² square units /π =
<em>451.93 square units</em>
Answer:
(3) (m - 16)(m + 4)
Step-by-step explanation:
Given the expression:
m^2 -12m - 64.
Using quadratic formula:
Then, the factored expression is:
(m - 16)(m + 4)
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
