Column 3= column 6 ==>equivalent
Answer B
The answer is 90 + 45 because BOC is a right angled triangle where angle BOC is 90 and angle BOK is 45 because 90 ÷2. A OK Is a right angled triangle so angle AOB is 90 as well so to find angle AOK we plus 90 and 45 which is 135 degrees.

Answer:
4cm
Step-by-step explanation:
given volume = 48πcm³
height = 9cm
r = ?
the formula for finding the volume of a cone = 1/3 πr²h
v = πr²h/3
make r" the subject of the formula
by cross multiplying,
3v = πr²h
divide both sides by πh
3v/πh =r²
r = √3v/πh
r= √3 × 48π/9π
π cancels π
r = √144/9
r = 12/3
r = 4cm
therefore the radius of the cone is 4cm
