What is a radius of this circle D=10

Mathematics
1 answer:
Orlov [11]3 years ago
5 0

THE RADIUS OF THE CIRCLE IS 15.7

To find the radius, we'll have to find, the CIRCUMFERENCE FIRST.

Circumference of a circle = π × Diameter

= π (3.14) × Diameter (10)

= 3.14 × 10

= 31.4

So, the circumference is 31.4

The RADIUS is HALF OF THE CIRCUMFERENCE.

Radius = 31.4 ÷ 2

= 15.7

THEREFORE THE RADIUS OF THE CIRCLE IS 15.7

Which of the following is the statement of the triangle inequality theorem?
kupik [55]

we know that

<u>The triangle inequality theorem</u> states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

so

Let

a,b,c------> the length sides of a triangle

The theorem states that three conditions must be met

<u>case 1)</u>

a+b > c

<u>case 2)</u>

a+c > b

<u>case3)</u>

c+b > a

therefore

<u>the answer is the option</u>

B. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

The figure shows a gas tank in the form of a rectangular prism that is 40% full. How many more gallons of gas will it take to fi
Ira Lisetskai [31]

Answer:

10.8 gallons

Step-by-step explanation:

First change everything to inches:

2.75 ft = 33 in

1.5 ft = 18 in

Volume of tank = lwh = (33)(18)(7) = 4158 in³

The tank is 40% full, so only 60% is need to fill it. To find 60%, multiply 4158 by 0.6 = 2494.8 in³

Now find out how much 2494.8 in³ is in gallons:

231 in³ = 1 gallon

1 in³ = 1/231 gallons

2494.8 = (1/231)(2494.8) gallons = 10.8 gallons
