Step-by-step explanation:
48×3= 144
48×3=144
to make it easier just add the number being multiplied the amount of times its being multiplied.
48+48+48=144
Answer:
Step-by-step explanation:
Given that,
The diameter of the pizza, d = 18 cm
We need to find the square cm of cheese layer does she need to put on the pizza.
We know that the area of the circle is given by :
Where
r is the radius of the circle
Here, r = 9 cm
So,
So, the area of the pizza is .
Answer:
The equation of the parabola is (x-2)^2 =8(y-2)
Step-by-step explanation:
Given focus is (2,4) and the directrix is y=0 so the parabola axis is parallel to y- axis.
Focus is (α,β+a) and the directrix is of the form y = β-a
so given focus is (2,4) compare (α,β+a)
here β+a = 4 and a=2 and β=2
now given directrix y = β-a = 2-2 = 0
now the general parabola is (x-α)^2 =4a(y-β) ...(1)
now substitute α =2 ,β=2 and a=2 above equation
The equation of the parabola is (x-2)^2 =8(y-2)
