A company is designing a new cylindrical water bottle. The volume of the bottle will be 147 cm ^ 3. The height of tbe water bottle is 7.5 cm. What is the radius of the bottle? Use 3.14 for pi

2.496cm

Step-by-step explanation:

Volume of the cylindrical water bottle. Can be calculated with the equation below

V=πr^2h

Where

h= height

r= radius

Then substitute the values into the equation we have

147= 3.14 × r^2 × 7.5

147= 23.565 r^2

Make r^2 subject of the formula

r^2= 147/ 23.565

r^2= 6.23

r= √6.23

r= 2.496cm

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
