Formula C= 2(3.14)(R)
We are looking for R first, so
=
——
2
r= 25.12
————
2(3.14)
r= 25.12
———-
6.28
r= 4
diameter= r(2)
4(2)= 8
THE DIAMETER OF THE CIRCLE IS 8

The unit of C is calories, m is for pounds, t is minutes. We supply these units in the equation.
calories = k (pounds)(minutes)
The unit of k should be equal to calories/(pounds x minutes). That is,
unit of k is cal/lb.min
Subst for f and t in...
9t+3ft+12 = 9×21 + 3×3×21 + 12 = 390
Answer:
✔️Ratio of weight to mass in simplest form: 49/5 or 49 : 5
✔️x = 110
Step-by-step explanation:
Since the ratio of weight to mass is constant, therefore we can use any pair of values from the table to find the ratio that represents the table. Let's pick the first row:
(20, 196)
Ratio of weight to mass = 196 : 20
= 196/20
= 49/5
Or 49 : 5
✔️Let's use this ratio/proportion to find x in the table
Ratio of weight to mass = 49:5
Thus:
1078/x = 49/5
Cross multiply
x*49 = 1078*5
49x = 5,390
x = 5,390/49
x = 110
