Answer:
414cm^2
Step-by-step explanation:
Given data
Base a= 9cm
Hence the expression for the surface area is
SA=2a^2+4ah
A=2*9^2+4*9*7
A=162+252
A=414cm^2
Hence the surface area is 414cm^2
C.
2.7 radians
2
2 is the slope of y=2x+3 and any line parralel would have the same slope. therefore the parallel slope would be 2
