The value of r in the equation r(61/2)=5(61/2)-3.5 is 4.88.
Given an equation r(61/2)=5(61/2)-3.5.
We are required to find the value of r in the equation.
Equation is like a relationship between two or more variable that are expressed in equal to form. The equation of two variables look like ax+by=c. It may be a linear equation, quadratic equation, cubic equation and many more depending on the powers of the variable present in that equation.
In our equation the variable is r.
The equation is given as:
r(61/2)=5(61/2)-3.5
r(61/2)=305/2-3.5
r(61/2)=(305-7)/2
r(61/2)=298/2
r=(298*2)/(2*61)
r=596/122
r=4.88
Hence the value of r in the equation r(61/2)=5(61/2)-3.5 is 4.88.

Answer:
2304π cm³
Step-by-step explanation:
The formula for the volume of a sphere is: 4πr³/3
The equation gave us the diameter so we can find the radius right away: 24 ÷ 2 = 12
Plug the radius in to the formula:
4π12³/3 = (4×1728π)/3
= 6912π/3
= 2304π

Answer:
6.14
Step-by-step explanation:
Find area of shaded region:
regtangle area - circle area = shaded area
Regtangle area:
3x3=9
Circle area:
Pi (3.14) x radius x radius= 3.14
area all together if shaded region
9-3.14=6.14
