Answer: C
Step-by-step explanation:
When you are finding the area, the formula is A= Pi R^2.
The radius is half of the diameter. To get a diameter of 6, you have to multiply 3 by 2.
Answer:
You find the area of all the faces of the square pyramid, then add them together to get the surface area.
Area = the top semicircle + the rectangle AEBD
= 1/2 pi*6^2 + 6*12 = 128.55 cm^2 to nearest 100th
Perimeter = 6pi + 12 + 2 pi * 3 = 49.70 cm
Y^2 -11y = 0
We can factor it:
y * (y -11) = 0
So y = 11, 0
Hello my Kings and Queens the answer would be 60 degrees because all angles of a triangle always add up to 180 degrees
