I say she is incorrect because the equation 9y+y9y+y should equal 19y if I am correct. I am sorry if im not correct but i believe she is incorrect
Answer:
Volume of cone = 209.44 cm²
Curved surface area of cone = 188.57 cm
Step-by-step explanation:
Given:
Height h = 8 cm
Slant height l = 10 cm
Radius r = 6 cm
Find:
Volume of cone
Curved surface area of cone
Computation:
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)π(5)²(8)
Volume of cone = 209.44 cm²
Curved surface area of cone = πrl
Curved surface area of cone = π(6)(10)
Curved surface area of cone = 188.57 cm
Yintercepts are where x=0
set to zero to solve
0^2+4y^2=16
4y^2=16
divide 4
y^2=4
sqrt both sides
y=+/-2
xintercept is where y=0
x^2+4(0)^2=16
x^2+0=16
x^2=16
sdqrtboth sides
x=+/-4
yintercepts are (0,2) and (0,-2)
xintercepts are (4,0) and (-4,0)
The length is 10 because this is a right triangle and based on the pythagorean theorem, the sum of the squares of the legs equals the square of the longest side.
6 squared plus 8 squared is 100, which is 10 squared.
The answer is 10.
1/2x = 2/3x - 8...multiply everything by common denominator of 6
3x = 4x - 48
3x - 4x = -48
-x = -48
x = 48 <== ur number
