Answer:
10
Step-by-step explanation:
523=4/3 pi r^3
124.86=r^3
5=r
d=2r
d=10
B.)28
because the width 6 times 2 is 12
the length 8 times 2 is 16
16 plus 12 = 28
It should be 13 as well
Because the arc length of CDE and ABCD are both 90 degrees. They share 20 degrees from arc CD and they already both have 70 degrees. So if the arc length is equal, the corresponding chords should be equal too.
Answer:
.
Step-by-step explanation:
3x - y = 17 .......A
10 × [x/5 + y/2] = 10 × 0
2x + 5y = 0 .......B
......A× 5 both 2 sides of equation
15x - 5y = 85 .....C
......B + ........C
2x + 15x = 0 + 85
17x = 85
x = 85/17
x = 5
put x value in ........A or .......B or ......C
you will receive y = -2
Answer:
the answer is 71.2
Step-by-step explanation:
4×4=16
6.9×2=13.8
13.8×4=55.2
55.2+16=71.2
