Find the area and the circumference of a circle with radius 6 m.
Write your answers in terms of it, and be sure to include the correct units in your answers.
(a) Area:
6 m
(b) Circumference:
Answer:
(a) 113.04m²
(b) 37.68m
Step-by-step explanation:
(a)
Area = πr²
=π(6)²
=36π
=113.04m²
(b)
Circumference = 2πr
2π(6) = 12π
=37.68m
Step-by-step explanation:
(a) πr^2= 22/7 * 6*6
= 113.1 m^ 2
(b) 2πr= 2*22/7*6
= 37.7 m
A bus can hold a total of 60 students. The bus is 73% full how many students are on the bus?

Find the value of a and the area of the triangle. Round to the nearest hundredth
Answer:
a = 6.65
Area = 15.84
Step-by-step explanation:
By cosine rule in the given triangle,
BC² = AC² + AB² - 2(AC)(AB)cos(C)
a² = 5² + 9²- 2(5)(7)cos(28°)
a² = 25 + 81 - 61.81
a = [tex]\sqrt{44.19}[/tex]
a = 6.65
Area of a triangle with given three sides = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Here, s = Average of lengths of all sides
a, b and c are the measures of the respective sides of the triangle.
s = [tex]\frac{6.65+7+5}{2}[/tex]
s = 9.325
a = 6.65, b = 5 and c = 7
Now substitute these values in the formula to get the area,
Area = [tex]\sqrt{9.325(9.325-6.65)(9.325-5)(9.325-7)}[/tex]
= [tex]\sqrt{9.325\times 2.675\times 4.325\times 2.325}[/tex]
= [tex]\sqrt{250.8313}[/tex]
= 15.838
= 15.84

How do you simplify the fraction 18/72
Answer:
1/4
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator GCD of 18 and 72 is 18
Divide both the numerator and denominator by the GCD 18 ÷ 18 / 72 ÷ 18
Reduced fraction: 1 / 4 Therefore, 18/72 simplified to lowest terms is 1/4.
