51/4 is the correct answer
Answer:
X=37
Step-by-step explanation:
Since they are vertical angles they are both equal to 80. Set the other side equal to 80 and solve for X, and you should end up with 37.
Answer:
x = -15
Step-by-step explanation:
x - 15 = -30
add 15 to both sides
x = -15
The surface area of a sphere of radius r is A = 4π*r^3.
Since the radius in this case is 7 cm (half the 14 cm diameter), the area of this sphere is
A = 4π(7 cm)^2, or 196π cm^2.
