Volume of sphere = 4/3πr<span>³
14.14 = 4/3 *22/7 *r</span>³

14.14 * 3/4 * 7/22 = r³

∛3.37 =r

1.499 = r

so 1.5 mm is the radius

Multiply (3c+2p)(3c-2p) what is the answer?

Len [333]

9514 1404 393

Answer:

9c² -4p²

Step-by-step explanation:

The product of a sum and difference of the same two terms is the difference of their squares:

(3c +2p)(3c -2p) = 3c(3c -2p) +2p(3c -2p)

= (3c)² -6cp +6cp -(2p)²

= (3c)² -(2p)² = 9c² -4p²

Find the area of the figure. Use 3.14 for pie . Round your answer to the nearest tenth.

gizmo_the_mogwai [7]

Answer:

538.3

Step-by-step explanation:

First of all find the area of the rectangle

L*W

15*30

450

Now find the area of semi circle

1/2 $\pi r^{2}$

Since radius is half a diameter divided 15 by 2=7.5

1/2 $\pi 7.5^{2}$ 7.5 times 7.5= 56.25

1/2*3.14*56.25

56 times 3.14 is 176.625 now multiply 176.625 by 1/2

Answer is 88.3125

Now add 450 to 88.3125

Final answer: 538.3125
