Figure=1rectangle+2 semicircles
1semicircle=1/2circle
2 (1/2 circles)=1 circle
figure=1 rectangle+1 circle
area of rectangle=legnth times width
area of circle=pir^2
so the width of the rectangle=diameter of the circle
widht=4
diameter=2r
d/2=r
width=d=4
4/2=r=2
area of circle=3.14 times 2^2
are of circle=3.14 times 4
aera of circle=12.56
area of rectangle=11 times 4
area=44
total=add them up
12.56+44=56.56 cm^2
Answer:
Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.
It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.
The absolute value of a number is its distance from zero. There can not be a negative distance from zero. Therefore, all absolute values are positive, no matter if the value inside them is positive or negative. So, B, C, and D can each be the absolute value of some number x, because they are all positive.
Hope this helps! :)
Answer:
Area of circle - Area of square
radius of circle is 8m
side of squre os 12m
Step-by-step explanation:
Area of circle is pie r^2
22/7 × 8 × 8
22/ 7 × 64
= 201.14m^2
Area of square is side ^2
12 ×12
= 144m^2
hence 201.14 - 144
= 57.14m^2 is the area of shaded figure
GOOD LUCK FOR THE FUTURE! :)
