I surely don't have any clue on how to that type of math sorry.
Formula of v. of sphere = (<span><span>4</span>π</span>r

)/3<span>
r = 3
pi = 3
(4 x 3 x </span>

)/3 = 113.1
Answer = 110cm
<span>CD's must be 40 or below, so CD's total≤ 40
If you already have 27, than 27+(number of CDs bought)</span><span>≤ 40
27+x=40(max)
x=(40-27)
x=13 CDs can be bought, at maximum
so (CDs purchased)</span><span> ≤ 13
Therefore, 15 CDs would be too many to fit in the rack </span>
Answer:
The length of each of the other two sides would be 3.1 cm
Step-by-step explanation:
<u><em>The options of the question are</em></u>
A. 3.1 cm
B. 3.2 cm
C. 4.2 cm
D. 6.1 cm
we know that
An isosceles triangle has two equal sides and two equal interior angles
Let
x -----> the length of each of the two equal sides in the isosceles triangle
The perimeter of one isosceles triangle is equal to

Remember that
To maximize the use of the wire, the perimeter of 6 earrings (3 pairs of earrings) must be equal to 50 cm
so

Solve for x




therefore
The length of each of the other two sides would be 3.1 cm
Answer:
105.5664, or 93 + 4 pi
Step-by-step explanation:
84 + 9 + 4 pi
equals 105.5664, or 93 + 4 pi
Break the shape into common shapes.
12 times 7 (rectangle) = 84
3 times 3 (square) = 9
