What is the volume of a sphere, to the nearest cubic inch, if the radius is 7 inches? Use π = 3.14.

1436.03 in³

Step-by-step explanation:

We can use the formula V = r³

Plug in 7 for r:

V = (7)³

Plug in 3.14 for pi:

V = (3.14)(343)

V = 1436.03 in³

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
