Hello There!
Surface area of a sphere formula:
4πr²
SA = 4π14.21²
SA = 2537.5mm³
Surface area of a cone formula:
1/3πr²5
SA = 1/3π3²15.1
SA = 142.3in³
Pyramid:
SA = 124.3
Hope This Helps You!
Good Luck :)

Answer: Area of a trapezium ABCD = {¹/₂ × (AB + DC) × h} square units. = ¹/₂ × h × (AB + DC) square units. You could have went to google and got the answers cause that what I did dummy
Answer:
137°
Step-by-step explanation:
Basically, its the reverse of question 1.
With angle x, you can find out that the opposite angle is 360 - 106 = 254°
the angle is twice the size of angle y as said in the corcle theorems.
254 divided by 2 = 137°
(please correct me if im wrong, i feel like im missing something)
Answer:
42
Step-by-step explanation:
This time, you'll be doing SOH.
sin (x) = 39/59=0.66
then do sin^-1 (0.66)
x = 42 degrees (think this is correct I hope)
0= -3x+9
-9=-3x
3=x
Final answer: x=3
There is only one zero because it is linear, and can therefore only cross the x axis once.
