Let
rA--------> radius of the circle A
rB-------> radius of the circle B
SA------> the area of the sector for circle A
SB------> the area of the sector for circle B
we have that
rA=5/2 ft
rB=9/2 ft
rA/rB=5/9-----------> rB/rA=9/5
SA=(25/36)π ft²
we know that
if Both circle A and circle B have a central angle , the square
of the ratio of the radius of circle A to the radius of circle B is equals to
the ratio of the area of the sector for circle A to the area of the sector for
circle B
(rA/rB) ^2=SA/SB-----> SB=SA*(rB/rA) ^2----> SB=(9/5) ^2*(25/36)π--->
<span>SB----------- > (81/25)*(25/36)------ > 81/36------
> 9/4π ft²</span>
the answer is
<span>the measure of the sector for circle B is (9/4)π ft²</span>
Answer:
17 to 24
25 to 32
Step-by-step explanation:
8-1=7
16-9=7
therefore it means we add 7 on the next number which is 17; to get 24,and also to the next number after 24 which is 25 to get 32
Answer:
Mr. Pham with 2/7
Step-by-step explanation:
2/7 = 0.286
1/4= 0.25
so 2/7 is ur correct answer.
25 - 4x = 15 - 3x + 10 - x
combine like terms
25 -4x = 25 -4x
add 4x to each side
25 = 5x
x= all real numbers
