You first need to break each shape down. for example in the top right corner you have a pyramid and a triangular prism. find the area for those two shapes and add them together and you will have the surface area for the entire shape
You have to take 60 degrees and add it to 90 degrees because that’s how much the box in the corner is worth
Then add those 2 together which is 150 after that’s subtract it by 270 which is 120
Answer: 120 degrees or 120
The formula for a circumference of a circle is 2πr
2 × π × 25 = 157
so your answer is A 157in.
I hope I've helped!
-3x + 4 > 5
-3x > 5 - 4
-3x > 1
x < 1/-3
x < -1/3
f(x)=-3x^2-1
f(-2)= -3(-2)²-1=-3·4-1= - 13
