Answer:
<h2>231in^3</h2>
Step-by-step explanation:
We know that the volume of a sphere/globe is given as
V=4
/3πr^3
but the circumference is expressed as
C=2πr
solving for r given that C=24
24=2*3.142r
24=6.284r
r=24/6.284
r=3.8in
put r=3.6 in the expression for volume we have
V=4
/3π(3.8)^3
V=4
/3π(55
V=(220.59*3.142)/3
V=693.12/3
V=231in^3
The volume of the globe is 231in^3
The answer is D. All the opposite sides are congruent.
Sum of the number and its of inverse equals 0.
<u>Answer:</u>
-348
<u>Step-by-step explanation:</u>
We are given the following arithmetic sequence and we are to find the sum of its first 12 terms:
1, -4, -9, -14, . . .
For that, we will use the formula for the sum of the arithmetic mean:
We know the value of the first term (
) but we need to find the value of 
. So we will use the following formula:
Substituting these values in the sum formula to get:
-348
We are given pattern 615,605,595.
Let us check differences of second term - first term and
Third term - second term
Second term - first term = 605 - 615 = -10.
Third term - second term = 595 - 605 = -10.
So, each time 10 is being subtracted from previous term.
So, the sequnace would be
<h3>615, 605, 595, <u>585</u>, <u>575</u>, <u>565.</u></h3>
