Pete needs to install a circular window with a radius of 7.25 inches. Which is the closest to the amount of glass he will need?
A) 22.77in cubed
B) 41.26in cubed
C) 45.53in cubed
D)165.05in cubed

)165.05

Step-by-step explanation:

7.25²=52.56

52.56*3.14=165.05

C) 45.53in cubed.

Step-by-step explanation:

One formula for finding circumference is C=r2(pi).

So, if you plug in the numbers,

= C=7.25(2)(3.14)

= C=14.5(3.14)

= C=45.53

So, the answer is 45.53in cubed after multiplying all of the numbers.

Hope this helps :)

(I'm not sure if it's right though because the answer is cubed.)

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

the answer is mp
