$19.4
Step-by-step explanation:
Simple Interest=SI
Principle(deposit)=P(97)
Rate= R(4/100=0.04)
Time= T(5)
SI=P•R•T
SI=97x0.04x5
SI=19.4
Interest earned = $19.4
The surface area formula is 4 x pi x r^2
Let the required number is 2x ,
According to the condition,
➡ 10 times the sum of half of 2x and 6 = 8

Therefore the value of x is -5.2
And, required number is -5.2
