I believe that the answer is 1845
the surface area of the cube is 1350
the surface area of the pyramid is 495
the total surface area is :

good luck
Ok so we know that the distance around the circle (or circumference) is equal to the diameter times pi.
This means that

d being the diameter,
This means that:

= 12.00028271
= 12 m
So the diameter of the circle is 12 metres.
Hope this helped
The answer is C
5.76 x 10 ^3 means you move the decimal 3 times:
57.6> 576.0> 5760
Y+ 2+ 6(y+6)
= Y+ 2+ 6y+ 36 (distributive property)
= Y+ 6y+ (2+ 36) (combine like terms)
= Y+ 6y+ 38
The final answer is Y+ 6y+ 38~
