Answer:
452.39 is the answer
Step-by-step explanation: Use the formula for the area of a sphere: 4 pi r^2, where R is the radius. R=6. Area=4 pi (6)^2=452.39=452.4 to the nearest tenth.
I think it is correct, but I don’t know what to do next.
Answer:
15/16.
Step-by-step explanation:
2 1/2 = 5/2 and 2 2/3 = 8/3 so we have:
5/2 / 8/3 Invert the 8.3 and multiply:
= 5/2 * 3/8
= 15/16.
Answer:
1) (-42,0)
2) 2x-y=4
3) y-2x=-3
Step-by-step explanation:
y=mx+b
y=3/7x+18
-18=3/7x
x=-42
(It may be wrong because I am sort of rusty on this stuff)
Answer:
Unpainted surface area = 514.28 cm²
Step-by-step explanation:
Given:
Side of cube = 20 Cm
Radius of circle = 20 / 2 = 10 Cm
Find:
Unpainted surface area
Computation:
Unpainted surface area = Surface area of cube - 6(Area of circle)
Unpainted surface area = 6a² - 6[πr²]
Unpainted surface area = 6[a² - πr²]
Unpainted surface area = 6[20² - π10²]
Unpainted surface area = 6[400 - 314.285714]
Unpainted surface area = 514.28 cm²
