Step-by-step explanation:

920 - 444 = x - 450

476 = x - 450

x= 476 + 450 = 926

x = 926

What is the surface area of the ice cream

galina1969 [7]

Answer:

$13194.7\ mm^2$

Step-by-step explanation:

The total surface area of a cone is given by:

Surface area = $\pi r(r+\sqrt{h^2+r^2} )$

where r is the radius of the cone, h is the height of the cone, l is the length of the cone = $\sqrt{h^2+r^2}$

Given that h = 136 mm, r = 60 mm /2 = 30 mm, l = 140 mm. Also the top of the cone is not included in the surface area, hence the surface area becomes:

$Surface \ area=\pi r(\sqrt{h^2+r^2} )=\pi rl\\\\Surface \ area=\pi (30\ mm)(140\ mm)=13194.7\ mm^2$

If Sarah is 24 years younger than her mother and if the um of their ages is 68, how old is Sarah? x best represents 1. Sarah's a

sukhopar [10]

Answer:

Sarah's age is best represented by M-24 or as the question used x-24 where the mother's age is best represented by M where the question used x.

Step-by-step explanation:

We are given that Sarah (S) is 24 years younger than her mother (M).

So S=M-24.

We are given that Sarah (S) and her mom's age adds up to 68.

So S+M=68.

We are going to solve this system by substitution since one of the variables is solved for. I'm going to plug first equation into second like so:

(M-24)+M=68 I replaced S with M-24.

M+M-24=68 Put like terms together.

2M-24 =68 Combined the like terms.

2M = 92 Added 24 on both sides.

M = 92/2 Divided 2 on both sides.

M = 46 Simplified the 92/2.

So her mother's age is 46.

We know that S=M-24 so S=46-24=22.

Sarah is 22 years old.

The endpoints of a diameter of a circle are A(3,2) and B(6,6). Find the area of the circle in terms of π.

Oksi-84 [34.3K]

Answer:

area of circle in terms of π is $\mathbf{Area=6.25\:\pi }$

Step-by-step explanation:

The endpoints of a diameter of a circle are A(3,2) and B(6,6). Find the area of the circle in terms of π.

The formula used to find area of circle is: $Area = \pi r^2$

We need to find radius of circle. For finding radius we will first find diameter of circle using distance formula.

Finding distance between points A(3,2) and B(6,6) using distance formula.

$Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have $x_1=3, y_1=2, x_2=6, y_2=6$

Putting values and finding distance

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(6-3)^2+(6-2)^2}\\Distance=\sqrt{(3)^2+(4)^2}\\Distance=\sqrt{9+16}\\Distance=\sqrt{25}\\Distance=5$

So, distance is 5, we can say that diameter of circle = 5

The formula used to find area of circle is: $Area = \pi r^2$

We need radius, so we know that r = d/2 so, radius = 5/2 = 2.5

Now finding area in terms of π

$Area = \pi r^2\\Area=(2.5)^2\pi \\Area=6.25\:\pi$

So, area of circle in terms of π is $\mathbf{Area=6.25\:\pi }$
