A bowl is in the shape of a hemisphere (half a sphere) with a diameter of 15 15 in. How can you find the radius if you know the diameter of the sphere? Find the volume of the bowl. Use 3.14 for pi π.

ANSWER: V=883.125 in^3

EXPLANATION:
*The radius is had the diameter. So, the radius is 7.5 because the diameter is 15.

V = 4/3 πr³

V = 4/3 (3.14)(7.5)³

V= 1766.25in³

*You found the volume of the entire sphere (1766.25in³). To find half, you divide by 2!

V=1766.25in³/2

V=883.125in³

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
