If someone could answer and explain this that would be great! TYSM guys! <3

The answer for part A is 49π cm² and part B is 81π in².

Step-by-step explanation:

In part A, 14cm represents the length of diameter of circle, in order to find its radius, you have to divide it by 2 which is 7cm. Next, you have to apply area of circle formula :

A = π × r²

A = π × 7²

A = 49π cm²

Part B :

A = π × 9²

A = 81π in²

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
