Me with my homework! determine the area of a circle whose diameter is 15 inches. use 3.14 for π. round to the nearest tenth. a. 47.1 in squaredb. 706.5 in squared c. 94.2 in squared d. 176.6 in squared

aera=pi*radius^2

diameter/2=radius

given tat diameter=15

iameter/2=15/2=7.5=radius

area=pi*radius^2=3.14*7.5^2=3.14*7.5*7.5=176.625 in^2

so answer is D

the anwser to this is d

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
