Answer:
<h2>The first option is correct 1675.5 cm^3</h2>
Step-by-step explanation:
Step one:
we are given the radius as
r=2cm, and the number of spheres is 50 in numbers
let us find the volume of one sphere and multiply the area by 50 to get the volume of the 50 spheres
Step two:
The volume of one sphere is 33.5in^3
Hence the volume of the 50 spheres will be
=33.5*50
=1675.7cm^3 approx.
Answer:
Triangle BDA
Step-by-step explanation:
Since triangle BDA seems to share congruent sides with triangle ACB they seem to be congruent
Cubic stack would mean all the sides are the same length.
The length of the side is given as 3 yards.
Volume = 3^3 = 3 x 3 x 3 = 27
Volume = 27 cubic yards.
Answer:
<h2><em><u> 42.8 in</u></em></h2>
Step-by-step explanation:
Step one:
given data
we are told that the expression for the depth of a lake after x years is given by
Required
The value of y when x= 4
Step two:
substitute the value of x in the expression to get y
<em><u>After 4 years the depth will increase by 42.8 in</u></em>
