131.88 or jus do radius times 2 so 21+ 21 = 42.
42 x pi(3.14) = 131.88
Answer:
C≈8.17cm
Step-by-step explanation:
C=2πr=2·π·1.3≈8.16814cm
Answer:
324π in.³
Step-by-step explanation:
The figure is a cone and a half sphere.
V = (1/3)πr²h + [(4/3)πr³]/2
V = (1/3)π(36 in.²)(15 in.) + (2/3)π(216 in.³)
V = [180π + 144π] in.³
V = 324π in.³
Hey there I see you need help well I am here to do just that 2/10 in its simplest form is 1/5 because you can divide both the denominator and the numerator by 2
