It’s A because I took this test
Answer:
The answer to your question is:
Step-by-step explanation:
a) There is no figure 0.
b) From one figure to the other there are 2 more cubes
c) Number of cubes = 3 + 2(n- 1)
where n is the number of figure
d)
Number of cubes in figure 100 = 3 + 2(100 - 1)
= 3 + 2(99)
= 3 + 198
= 201
The answer is c all the others are 1/3 fractions
Answer:
8 sides
Step-by-step explanation:
let x be the exterior angle then 3x is the interior angle
interior angle + exterior angle = 180° , then
x + 3x = 180
4x = 180 ( divide both sides by 4 )
x = 45
the sum of the exterior angles of a polygon = 360°
since the polygon is regular with each exterior angle = 45°, then
number of sides = 360° ÷ 45° = 8
Answer:
Step-by-step explanation:
The formula for determining the volume of a sphere is expressed as
Volume = (4/3) × πr³
The volume of the given sphere is expressed as 288π inches³. It means that
(4/3) × πr³ = 288π
4r³/3 = 288
4r³ = 3 × 288 = 864
r³ = 864/4 = 216
Taking cube root of both sides, it becomes
r = 6
The formula for determining the surface area of a sphere is expressed as
Area = 4πr²
π = 3.14
Therefore,
Surface area = 4 × 3.14 × 6² = 452.16 inches²
