Answer:
62°
Step-by-step explanation:
There should be 180° in a straight line.
63+55=118.
180-118=62
My deepest apologies if it is incorrect.
Answer:
a+2b
Step-by-step explanation:
2(a+2b) -a-2b
2a+4b-a-2b
a+2b
V(cylinder)= πr²h
d=2r,
d is diameter, r is radius.
When diameter is tripled, a new diameter D=3d,
new radius R=3d/2=(3*2r)/2=3r
R=3r
V(new cylinder)= πR²h = π(3r)²h=9πr²h
V(new cylinder)/V(cylinder)=9πr²h/πr²h=9
Volume new cylinder 9 times more the volume of old cylinder.
