You have to multiply on this one because example you go to the restaurant and eat so you pay but you have to put tips for the workers so its saying how much was total in all plus the tips
Answer:
volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
Step-by-step explanation:
The formula to find volume of sphere is:
Volume of sphere = 4/3 π r^3
if radius is divided by 2 i.e r/2
Volume of sphere if r/2 = 4/3 π (r/2)^3
= 4/3 π r^3/8
= (4/3 π r^3) / 8
= (Volume of sphere 1)/8
So, volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
Area of Triangle: bh1/2[base x height x 1/2(divide by 2)]
Plug in- 10 x 7 x 1/2
70 x 1/2

Height, h of the cone is 3V/πr²
Step-by-step explanation:
- Step 1: Find formula for height.
Volume, V = 1/3 πr²h, where r is the radius and h is the height of the cone.
Cross-multiply to find formula for height.
∴ Height, h = 3V/πr²
