Answer:
r=2.5
Step-by-step explanation:
C=2pi*radius
Substitute 15.7 in for c and 3.14 in for pi
15.7=2(3.14)*r
15.7=6.28r
Divide by 6.28
r=2.5
Hope this helped!
Answer:
x
Step-by-step explanation:
2/x = 6/3x
6/3x + 10/3x = 16/3x
Total surface area
=[ 2πr x 11 ] + πr²
=[ 2 x (22/7) x 3.5 x 11 ] + 2[ (22/7) x 3.5² ]
=154 + 2(15.393)
=184.786 in²
Answer:
C
Step-by-step explanation:
D=m/v
Rearranging the formula
v=m/D
V=1000/13.56
V=73.69 cm3
Answer:
The Square root is 6/13
Step-by-step explanation:
You just have to find a number when multiplied by itself = the number you are given.
