Answer:
Circumference is about 185.26 cm.
Area is about 2732.585 
Step-by-step explanation:
Circumference = 2πr
2 x 3.14 x 29.5 = 185.26
Area of a circle = π
3.14 x 29.5 x 29.5 = 2732.585
The answer is C . cube 2
Explanation:
Using PEMDAS its Parentheses, exponents ,multiple then divide and add , subtract
The GCF is 5x because 5x goes into all the sets.
The final grade of fran can be calculated
by multiplying the corresponding percentage of his average homework, quizzes
and tests, then sum it up and it is now the final grade of fran.
Final grade = (0.10 x 92) + ( 0.20 x 68) +
(0.70 x 81)
<span>Final grade = 79.5 </span>
DC/AC=EC/BC
x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long
10/16=DE/AB, DE=y
10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3
