If the radius of a circle is 15, what will be the area of the circle?

751.124

Step-by-step explanation:

area of a cricle is

πr^2

take π to be 22÷7

A= πr^2

A=22÷7*15*15

A=22÷7*225

7 divides 225

= 34.142

22*34.142

A= 751.124

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
