The volume of the spherical piece is 288.55 cm³.
Solution:
Diameter of the sphere = 8.2 cm
Radius of the sphere = 8.2 ÷ 2 = 4.1 cm
The value of π = 3.14
Volume of the sphere 
= 288.55 cm³
The volume of the spherical piece is 288.55 cm³.
Answer:
2 mph
Step-by-step explanation:
time = distance / speed
Let c represent the rate of the current. Then the upstream rate of the boat relative to the shore is (5c -c) = 4c, and the <em>upstream time</em> is ...
... 12/(4c) = 3/c.
Likewise, the downstream rate is (5c +c) = 6c, and the <em>downstream time</em> is ...
... 12/(6c) = 2/c.
The <em>total time</em> is the sum of upstream and downstream times:
... 3/c +2/c = 2.5
... 5/c = 2.5 . . . . . . combine terms
... 5/2.5 = c = 2 . . . multiply by c/2.5
Answer:
$70.33
Step-by-step explanation:
sticker price = $93.78
discount coupon in percentage = 25%
Thus, discount will be 25% of sticker price
discount amount = 25% of $93.78 = 25/100 * $93.78 = $23.45
Thus, amount paid = sticker price - discount amount = $93.78-$23.45
amount paid = $70.33
actual cost to you will be what after discount applied is $70.33
