Answer:
42.43 
Step-by-step explanation:
Given:
A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.
Question asked:
What is the area of the shaded region as shown in the figure ?
Solution:
First of all calculate area of circle and then area of rectangle:-
<u>As here length an width both are 11 cm, we can say that this is a square.</u>
<u />
Now, area of shaded region = Area of square - Area of circle
= 121 - 78.571 = 42.429
Therefore, the area of the shaded region will be 42.43
Answer:
<h2>x=2</h2><h2>y=4</h2>
Step-by-step explanation:
5x-y=6
2x+y=8
add them up
7x=14
divide by 7 to get x
x=2
fit it into both equation
y=4
(a) It is leaking 18 liters per minute.
Explanation : From 15 minutes to 20 minutes, your starting point at 15 is 590 liters and at 20 you have exactly 500. Next you have 25 which is now at 410. So it's leaking 90 liters every five minutes, so of course dividing the two (90 ÷ 5) you get 18.
(a)² it increases for about the same time that it would decrease of course.
(b) The vat started at 860 liters before they started draining it.
Explanation : Well, all it takes is just working backwards, add 90 liters to the liters at 15 minutes and deduct five minutes from 15. Do this process until you arrive at 0. It's simple
Answer:
Step-by-step explanation:
Two triangles are congruent by AAS postulate if two adjacent corresponding angles are congruent and the next adjacent sides to any of the angles is are also congruent. The adjacent sides should not be in between the two congruent angles.
From the triangles RQS and UTV
The adjacent side to 
is RQ and for 
is UT.
Similarly, the adjacent side to 
is QS and for 
is TV.
So, the possible sides that could be congruent by AAS postulate are:
or 
So, the correct option is
Answer:
2d or 2 dimensional is the answer i think
Step-by-step explanation:
since area is measured for 2d shapes and surface area is just finding the area of each side separately and adding it together
