The surface area of a sphere is π x 4 x radius²
so let the radius be r
π x 4 x r² = 2122.64
r = 13 inches
Answer:
210 m
Step-by-step explanation:
the largest interior angle will be the front of largest side of triangle
X^2 -6x +1 = 0
a=1
b = -6
c = 1
Use the quadratic formula
x = [-b +- sq root (b^2 -4ac)] / 2a
x = [--6 +- sq root (36 - 4)] / 2
x = [ 6 +- sq root (32)] / 2
sq root (32) = 5.657
x1 = [ 6 + 5.657] / 2
x1 = 11.657 / 2
x1 =

<span>
5.8285

x1 = 5.82 (to nearest tenth)
x2 = [ 6 - 5.657] / 2
x2 = .343 / 2
x2 = .1715
x2 = .2 (to nearest tenth)
Answer:
Options A, D and F
Step-by-step explanation:
From the picture attached,
lines 'l' ad 'm' are the parallel lines and line 't' is a transversal intersecting each line at two different points.
From the angles formed at the points of intersection,
∠5 ≅ ∠8 [Vertical angles]
∠5 ≅ ∠4 [Alternate interior angles]
∠5 ≅ ∠1 [Corresponding angles]
Therefore, Options A, D and F will be the correct options.
