To find the surface area of a sphere, the formula is 4 pi r^2
with r being 1/2 meter (as diameter = 2r = 1) the surface area

= 4 * 3.14 * 0.5^2 = 3.14 m²

surface area = 4 x pi x r^2

diameter is 1, thus radius = 1/2 = 0.5

4 x 3.14 x 0.5^2 = 3.14 square meters

Zina [9171]
Answer: B. Accurate but unreliable. Step-by-step explanation: A study is deemed "reliable" if it yields consistent results upon repeated trials. When the experiment is performed numerous times, it produces the same outcome each time. On the other hand, an experiment is considered "accurate" when it correctly reflects the right outcomes through proper procedures and methods. In this instance, the research evaluating a new screening method for early detection of prostate cancer yielded results that were "accurate but unreliable" because the test results were not consistent.

An Olympian swam the 200-meter freestyle at a speed of 1.8 meters per second. An Olympic runner ran the 200-meter dash in 21.3 s
zzz [9080]
Velocity = Distance/Time

Runner's Speed = 200/21.3 = 9.4 m/s

Swimmer's Speed = 1.8 m/s

9.4 - 1.8 = 7.6 m/s

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures cre
Svet_ta [9500]
Linear pairs consist of adjacent angles that add up to 180 degrees, making them supplementary.
Vertical angles, on the other hand, are equal in measure.

When two lines intersect, and if you have the measure of one of the four resulting angles, suppose one angle has a measure of k degrees. This implies that the vertical angle also measures k degrees.
The other two angles each create a linear pair with the angle of k degrees, meaning each of these angles is complementary to it and each measures (180 - k) degrees.
