Answer:
10+3pi
Step-by-step explanation:
The perimeter of of the shaded region is
AC+CT+marcSBT+SA
*Finding AC
The diagonals of a rectangle are equal is measurement. Since RB is a radius of the circle, then RB is 6. Since AC and RB are both diagonals of the rectangle, then AC is also 6.
*Finding CT
CT=RT-RC where RC is the width of the rectangle
Also RT is a radius so we have that
CT=6-RC
*Finding marcSBT
The circumference of a whole circle is 2pi*r.
We have a quarter of this with r=6.
1/4*2pi(6)
1/4*12pi
3pi
*Finding SA
SA=RS-AR
RS is a radius of the circle and AR is the length of the rectangle.
So we have that this can be rewritten as
SA=6-AR
Let's put these parts together:
6+6-RC+3pi+6-AR
Simplifying:
18-RC-AR+3pi
18-(RC+AR)+3pi
18-8+3pi (Remember length plus width equal 8)
10+3pi
Answer:
I'm pretty sure the answer is 49.
Step-by-step explanation:
If you make a graph and use letters to stand for each side dish there would be 49 different combinations
Answer:
Part 1) The area of the structure is
Part 2) The slab will contain of cement
Step-by-step explanation:
Part 1) Find the area of the structure
we know that
The area of the structure is equal to the area of rectangle plus the area of semicircle
<u><em>Find the area of rectangle</em></u>
The area of rectangle is equal to
we have
substitute
<u><em>Find the area of semicircle</em></u>
The area of semicircle is
we have
substitute
<u><em>Find the area of the structure</em></u>
Adds the areas
Part 2) If the structure is 6 in thick, how many cubic feet of cement will the slab contain?
Remember that
Convert inches to feet
<u><em>Find the volume of the structure</em></u>
To obtain the volume , multiply the area by 0.5 ft (thick)
so
Answer:
2 times 8 is 16. 16 minus 4 is 12 plus 5 is 17. answer is 17.
Step-by-step explanation:
4x^3-7- that'll be the equation
2.5- that'd be your answer (decimal form)
