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.
Given:
In triangle XYZ, x = 27 cm, y = 79 cm and .
To find:
The length of z.
Solution:
In triangle XYZ, using the Law of cosine, we get
Putting the given values in the above formula, we get
Taking square root on both sides.
Approx the above value to the nearest number and side length cannot be negative. So,
Therefore, the length of z is about 102 cm.
Well first of all, if one angle is 95 degrees, then both other angles MUST be acute.
An infinite number of triangles can be made, just as long as the other two angles add up to 85 degrees.
KL + LM = KM
(8x - 5) + (6x + 3) = KM
(8x + 6x) + (-5 + 3) = KM
14x - 2 = KM
It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
