Answer:
Exact area: 39.2π cm²
Approximate area: 123.2 cm²
Step-by-step explanation:
The area of a circle is πr².
A full circle can be thought of as a sector of a circle with 360° of central angle. For a sector of a circle with a central angle of n°, multiply the area of the circle by the fraction n°/360°.
The formula for the area of a sector of circle with central angle n° and radius r is
A = (n°)/(360°) × πr²
Here we have n = 72; r = 14 cm
A = (n°)/(360°) × πr²
A = (72°)/(360°) × π × (14 cm)²
A = 39.2π cm² = 123.2 cm²
Answer:
The answer is 2876.25
Step-by-step explanation:
The question said x is ten
so 7x means 7*10
93x means 93×10
divided by 3.2x which means 3.2x which is 3.2×10
when u write it in an equation format it will look like this 70+930÷32
Ur answer should look like this 2976.25
The density of water is : 1 kg / lit
1 lit = 1 dm³
1 ml = 1 l / 1000
1 l = 1000 ml
1 kg = 1000 g
1 kg / l = 1000 g / 1000 ml = 1 g/ ml = 1 g / cm³
Answer: C ) 1 g / cm³
Answer:
5, 25, 109
Step-by-step explanation:
5, 25, 109, 2725 divided by 5, 5, 109, gives no remainder. They are integers and prime numbers of 2725, they are also called composite number.
Number 3 is x=5 and number 4 is x=63
