Answer:
π x³ /12 is the volume of the cone if A cone has a height of x and a diameter of x
Step-by-step explanation:
The base diameter and the height of a cone are both equal to x units
Diameter of cone = x units
Radius = Diameter /2
=> Radius of cone = x/2 units
Height of cone =x units
Volume of cone = (1/3) π r²h
r = radius h = height
=> Volume of cone = (1/3)π (x/2)² * x
= (1/3) π (x²/4) * x
= (1/12) π x³
= π x³ /12 cubic units
A rhombus<span> has </span>rotational symmetry<span>. It is a </span>symmetric<span> shape that can be rotated and still appear the same. A </span>rhombus<span> has two-fold </span>symmetry<span>, meaning that is can be rotated 180 degrees and appear the same.</span>
Answer:
x ≈ 9.5 , y ≈ 15.3
Step-by-step explanation:
sin32° = 
= 
( multiply both sides by 18 )
18 × sin32° = x , then
x ≈ 9.5 ( to the nearest tenth )
cos32° = 
= 
( multiply both sides by 18 )
18 × cos32° = y , then
y ≈ 15.3 ( to the nearest tenth )
Answer:
Step-by-step explanation:
for right-angled triangle: a^2 + b^2 = c^2
given a = 5 n b = 10
c^2 = 5^2 + 10^2
= 25 + 100
= 125
c = sqrt(125)
= 5*sqrt(5)
