Answer: The number is 12
Step-by-step explanation:
n=number
2n-8=16
2n=24
n=12
Since we know there are π radians in 180°, then how many radians are there in 153°?
Answer: 112.5 square units
Step-by-step explanation:
I think:
For the triangle:
1/2base(height) = 1/2(9)(7)= 31.5 sq. Units
For the small rectangle:
Length x width= 3 x 9 = 27 sq. Units
For the larger rectangle:
The length must be 16 - 7 - 3 = 6
So length x width = 6 x 9 = 54 sq units
Now add them together:
31.5 + 27 + 54 = 112.5 square units
V = 297 for a square pyramid, I hope its right..
Its C because the 18in is the height, the 12in is the width, the 24in is the length. Which you just multiply together.
