Answer: 76.35in²
Step-by-step explanation:
Circumference of a circle = 2πr or πd , while area is πr².
To find the area we must first of all find the radius if the circle using any of the formula above.we then equate 31 to 2πr and then solve for r.
31 = 2πr , where π = 3.142 or 22/7
r = 31/2 x 3.142
= 31 /6.284
= 4.93in
To find the area, substitute for r in the formula above,
Area = πr²
= 3.142 x 4.93²
= 3.142 x 24.30
= 76.35in².
Yeah I think so I just took a wild guess and looked at my measurement sheet
To determine the nth term of sequence, first we need to know what type of sequence is it. It can be an arithmetic sequence or a geometric sequence. For an arithmetic sequence, the nth can be determined by the formula,
an = a1 + (n-1)d
For a geometric sequence,
an = a1r^n-1
Hope this answers the question.
Answer:
product is 432
Step-by-step explanation:
(-2)(-4)=8
(-6)(-9)=54
(8)(54)=432
Answer:
mode = 5 because 5 have the largest frequency
median = 5 the 9th and 10th number is 5
mean = 97/4 = 4.65 or 4.7
mean = 4.7, median = 5, mode = 5
