Answer:
Area = πx² + x² or x²(π + 1)
Step-by-step explanation:
The area of the heart = area of a circle + area of the square
Note:
1. The 2 semicircles makes 1 full circle
2. The diameter of the circle = the side length of the square
Thus:
Area of the heart = πr² + s²
Where,
r = x
s = x
Formula for area of the heart = π(x²) + x² = πx² + x²
Area = x²(π + 1)
Answer:
The one which has a height of 3 units. H=3
Step-by-step explanation:
Well, the volume of pyramid is equal to the area of base multiply by the height of pyramid and divide by 3. Writing as a formula it can be expressed as V=(A*H)/3 where V is volume of pyramid, A is area of base and H is the height of pyramid. If V=15 cubic units and A=15 square units, H should be equal to 3 (to be cancelled out by 3. Please look at formula above) in order to make V=15.
A) x = 3y+6
3y = x-6
divide both sides by 3.
y = (x/3) -2
b) x = 5y-10
5y = x+10
divide both sides by 5.
y = (x/5) +2
c) x = y^2
square root both sides.
y = sqrt(x)
d) x = 2y^2 -4
x+4 = 2y^2
divide both sides by 2.
(x/2) +2 = y^2
square root both sides.
y = sqrt((x/2)+2)
e) x = (y-5)^2
square root both sides.
sqrt(x) = y-5
y = sqrt(x) +5
