Answer:
2
Step-by-step explanation:
Answer:
vol of cylinder = per. of base x height + 2 (area of base)
area of base = pi x r^2
4pi = pi r^2
4=r^2
r=2
per of base = 2 x pi x r
2xpix2=4pi (same as area cause 2x2 and 2^2 is the same thing)
4pi + 2(4pi)
4pi + 8pi
<u>12pi = volume</u>

angle = 37°
complementary angles have a sum of 90°
the angle whose complement is 53° = 90° - 53° = 37°
Answer:
≈ 78.55 cm
Step-by-step explanation:
Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is
= , that is
= ( cross- multiply )
110C = 8640 ( divide both sides by 110 )
C = ≈ 78.55 cm ( to 2 dec. places )
