C=2pir
area=pir^2
given
c=25.12
25.12=2pir
pi=3.14
25.12=2(3.14)r
25.12=6.28r
divide both sides by 6.25
4=r
sub into other
area=pir^2
area=pi4^2
area=16pi
area=16(3.14)
area=50.24
the area is 50.24 square cm
Answer:
8x -8 hope this helped
Step-by-step explanation:
3x+1 + 3x + 1= 6x+2
x-5 + x-5 = 2x - 10
6x+2 +2x-10= 8x-8
Answer:
No, it does satisfy the Pythagorean Theorem
Step-by-step explanation:
In right triangle a² + b² = c²
Where a and b = legs and c = hypotenuse
The given measures of the legs are 3 and 7 and the given measure of the hypotenuse is √57
Which means that if this is a right triangle then 3² + 7² = √57²
3² = 9
7² = 49
√57² = 57
9 + 49 = 58
we're left with 57 ≠ 58 which is not true, meaning that , that is not a right triangle
3x^2 -6x + 6 :) hope this is alright
