Answer- 50.63
A= πr^2
A is 204 so 204= πr^2
Make are R the subject and the answer of the radius will be 8.06.
The equation for circumference is 2 πr and now we have R so just substitute it into the equation and the answer is 50.63
Answer: 13/4
Step-by-step explanation:
3rd one
Jim is 19
let fathers age be x then mothers age = x - 5 and Jim's age is
(x - 5)
Total their ages and equate to 100
x + x - 5 +
(x - 5 ) = 100
multiply through by 2 to eliminate the fraction
2x + 2x - 10 + x - 5 = 200
5x - 15 = 200 ( add 15 to both sides )
5x = 215 ( divide both sides by 5 )
x = 43
father is 43 years, mother is 38 and Jim is 19
