Answer:
Step-by-step explanation:
<u>3/4 left and 1/7 of that eaten:</u>
- 3/4 - 3/4(1/7) =
- (3/4) (1 - 1/7) =
- (3/4)(6/7) =
- 18/28 =
- 9/14
One way is that you can just factor it out: (x+2)(x+2)(x+2)
For the first pair, you get

.
Then do

*

That will be

So the answer is 6

Answer:
Area of the circle is 6.25π sq.unit
Step-by-step explanation:
The centre of the circle is at the mid point of a diameter. Th mid point of the diameter is at (5+22,5+12)or(72,3),which is centre. Radius is the distance from end point (5,5)to centre (72,3)∴r=√(5−72)2+(5−3)2=√1.52+4=√6.25=2.5∴
Area of the circle is Ac=π⋅r2=π⋅2.52=6.25π sq.unit[Ans]
