Answer:
the answer is
A
Step-by-step explanation:
Area of the sphere ≅ 339.62 in².
<h3>What is Sphere?</h3>
A sphere is a geometrical object in three-dimensional space that is the surface of a ball. Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.
Area of sphere = 4
diameter d = 2r
Given that,
diameter d = 10.4 , r =5.2 in
then, Area of sphere = 4
= 4×3.14×5.2×5.2
≅ 339.62 in²

Answer:
85 hours
Step-by-step explanation:
Number of hours per day = 13 hours
Number of days = 6
Number of hours worked for 6 days = 6 days × 13 hours
= 78 hours
then he worked 7 hours
Total Number of hours worked = Number of hours worked for 6 days + 7 hours
= 78 hours + 7 hours
= 85 hours
Total Number of hours worked = 85 hours
Answer:
Type A
Explanation:
Gasoline used <u>Per</u> mile
Type 1 ⇒ 106/5 = 21.2
Type 2 ⇒ 204/10 = 20.4
Type 3 ⇒ 298/15 = 19.9
Type 4 ⇒ 392/20 = 19.6
Notice that Type 1 is using less gasoline while travelling farther miles. Hence, Type 1 is the answer.
33/8 because 3 4/8 +5/8=3 9/8 and 3x8=24+9= 33
