Answer:
The coaster’s radius is 5 cm
Step-by-step explanation:
Drink Coaster has a circular shape.
Area of a circle = π*r²
so, area of the drink coaster = π x (Radius of the drink coaster)²
Given that Area of the drink coaster is 78.5 cm²
∴ 78.5 cm² = π*r²
Also we are to use 3.14 for π
∴ 78.5 cm² = 3.14*r²
r² = 78.5 cm² / 3.14
r² = 25 cm²
r = cm
r = 5 cm
Hence, the coaster’s radius is 5 cm
Answer:
The answer is B.
Step-by-step explanation:
Answer:
1) x=6, y=-6 which is (6,-6) as an ordered pair
3) x=10, y=-1 which is (10,-1) as an ordered pair
Step-by-step explanation:
Question 1:
<u>Solve them like an addition problem:</u>
-4x-2y=-12
4x+8y=-24
________
(-4x+4x)+(-2y+8y)=(-12+-24)
0x+6y=-36
6y=-36
y=-6
<u>Plug value of y into one of the original equations:</u>
4x+8(-6)=-24
4x-48=-24
4x=24
x=6
Question 3:
<u>Solve them like an addition problem:</u>
x-y=11
2x+y=19
_______
(x+2x)+(-y+y)=11+19
3x+0y=30
3x=30
x=10
<u>Plug value of x into one of the original equations:</u>
10-y=11
-y=1
y=-1
