i am not too sure if i am correct in this but i will give it a go. i apologise if i am incorrect. In finding the diameter the equation C/π. in finding the radius the equation is (C/π)/2

Part 1
Q2) c=650πcm
650 X π= c so d must be 650cm
Q4) c=241πcm
241 X π= c so d must be 241
Q6) c=802cm
c/π=d =802/π= 255.28cm (2DP)
Q8) c=962cm
c/π=d = 962/π= 306.21cm (2DP)

Anna11 [10]

Answer:

$2125 interest accumulated at the end of 10 years .

Step-by-step explanation:

Formula

$Simple\ inerest = \frac{Principle\times Rate\times Time}{100}$

As given

An investor puts $2,500 into a life insurance policy that pays 8.5% simple annual interest.

Principle = $2500

Rate = 8.5 %

Time = 10 years

Putting all the values in the formula

$Simple\ inerest = \frac{2500\times 8.5\times 10}{100}$

$Simple\ inerest = 25\times 8.5\times 10$

Simple interest = $ 2125

Therefore the $2125 interest accumulated at the end of 10 years .
