Answer:
36
Step-by-step explanation:
Let
rA--------> radius of the circle R
rB-------> radius of the circle S
SA------> the area of the sector for circle R
SB------> the area of the sector for circle S
we have that
rA=3 ft
rB=6 ft
rA/rB=3/6----> 1/2----------->
rB/rA=2
SA=2π 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=(2) ^2*(2π)--->
SB----------- > 8π ft²
the answer is
the area of the sector for circle S is 8π ft²

I took the quiz
Answer:
-1199
Step-by-step explanation:
To solve this, we must use PEMDAS
1. using this, we see that we must first solve anything having to do with exponents so:
4^2 = 16
2. Then we must solve any multiplication or division (whichever comes first). So in this case:
5 x 243 = 1215
3. We are now left with 16 - 1215 so we simply subtract
16 - 1215 = -1199
Answer is 3
Step-by-step explanation:
first what you do is you rearrange the numbers so the eqaution is -2x+4=-2
SO what you do is (4) - 4 to cancel it out then you do the same thing on the other side so (-2)-4=-6 so the equation now is -2x=-6 then you divide -2 to cancel it out and you do the same thing -6 divide by -2 is 3 so the answer is 3
