Scorpion4ik [409]

Answer:

Area of the circle= $200.96 km^2$

Step-by-step explanation:

Area of a circle= $\pi *r*r$

For radius(r)=8 km

The area of the circle is :

= $\pi *8*8$

As:

$\pi =\frac{22}{7}=3.14$

Area of the circle:

$=3.14*8*8\\\\=3.14*64\\\\=200.96km^2$

The Area of the circle with the radius of $8km$ is $200.96 km^2$

Degger [83]

Should be 1204.75? use this answer to check your work!

My work:
14 times 18 (since there’s two triangles) = 252
36 times 28 = 1008
6.5 times 8.5 = 55.25

(1008 + 252) - 55.25 = 1204.75

there are 104 red candies in a candy machine. this represents 26% of the candy in the machine. how many total are in the candy m

Alborosie

There are 400 candies in the machine.

Step-by-step explanation:

Given,

Number of red candies in machine = 104

This represents 26% of the total candies.

Let,

x be the total candies in the machine.

According to statement;

26% of x = 104

$\frac{26}{100}*x=104\\0.26x=104$

Dividing both sides by 0.26

$\frac{0.26x}{0.26}=\frac{104}{0.26}\\x=400$

There are 400 candies in the machine.
