Answer:

220 degree

Step-by-step explanation:

Given the radius=18cm , pi=3.14.. , area=198π

Area of a sector =∅×π×r²/360

or,198π=Θ×π×r²/360

or,Θ=360×198π/πr²

∴Θ=220°

Answer:

B. 314 cm³

Step-by-step explanation:

We are given that,

Height of the cone = 12 cm

Radius of the cone = 5 cm

<em>Since, we need to fill the cone with the cement. So, we will find the volume of the cone.</em>

So, Volume of the cone = $\frac{1}{3}\pi r^{2}h$

i.e. Volume of the cone = $\frac{1}{3}\pi 5^{2}\times 12$

i.e. Volume of the cone = $\frac{1}{3}\times 3.14 \times 25\times 12$

i.e. Volume of the cone = $\frac{942}{3}$

i.e. Volume of the cone = 314 cm³

Hence, the amount of cement they can put in each cone is 314 cm³.

How to find the value of x

stealth61 [152]

Answer:

×=1

Multiply both sides of the equation by 12, the least common multiple of 4,3.

3x+4(x−1)=3

Use the distributive property to multiply 4 by x−1.

3x+4x−4=3

Combine 3x and 4x to get 7x.

7x−4=3

Add 4 to both sides.

7x=3+4

Add 3 and 4 to get 7.

7x=7

Divide both sides by 7.

Divide 7 by 7 to get 1.

x=1
