The area of a circle is 706.5 what is the radius?

15units

Step-by-step explanation:

Area=pi×r², where r is the radius.

706.5=3.14×r²

r²=225

r=15units

r = 15 units

Step-by-step explanation:

hello :

The area of a circle is : A= πr²   r is the radius

πr² = 706.5

r² = 706.5/3.14 = 225

r² = 15²

so  :   r = 15 units

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
