The area of the circle is 28.26
<u>Step-by-step explanation:</u>
Given that,
The diameter of the circle = 6
The formula to find the area of the circle is given by,
Area of the circle = πr²
where,
- r is the radius of the circle
- π has the default value of 3.14
The steps to find the area of a circle is to square the radius or multiply it by itself. Then multiply the squared radius by 3.14 to get the area.
Now, to find the radius = diameter /2
Radius = 6/2
r = 3
Substitute r = 3 in the area formula,
Area of circle = (3.14) × (3)²
⇒ 3.14 × 9
⇒ 28.26
Therefore, the area of the circle is 28.26
Answer: B {x:x<=9
Step-by-step explanation:
Step-by-step explanation:
First, let's find out how many tiles Mike needs.
Mike's kitchen is 75sqft, each tile covers 2.25sqft, so 75sqft/2.25sqft=33.3333...,
multiply that number by the cost per tile and round to the nearest hundredth.
Answer:
x = 70
Step-by-step explanation:
180 - 112 = 68
2x + 2x + 12 + 68 = 360
4x + 80 = 360
4x = 360 - 80
4x = 280
x = 280/4
x = 70
2x = 2*70 = 140
2x + 12 = 2*70 + 12 = 152
180 - 140 = 40
112 + 40 = 152
180 - 152 = 28
112 + 28 = 140
