Answer:
X = 18
y = 9
Step-by-step explanation:
Basically the 2 diagnols bisect each other making them congruent. so that makes
x-3 = 15 and y + 3 = 12
simplify and
the. you simplify and get x = 18 and y =9

Answer:
V ≈ 68.63 cm³
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V =
πr³
the volume of a hemisphere is half the volume of a sphere, so
V =
×
πr³ =
πr³ , then
V =
π × 3.2³
=
π × 32.768
≈ 68.63 cm³ ( to 2 dec. places )
Answer:
incorrect is They have a sum of -14
