Formula for circumference of circle:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer: Circumference of the circle is 25.1 cm (Rounded to 1 decimal place)
Divide capacity by sections:
5782 / 24 = 240.9167
The number of seats in each section is needs to be a whole number so there are 240 seats per section:
240 seats per section x 24 sections = 5,760 seats.
Priority seats is capacity - total section seats:
5782 - 5760 = 22
There are 22 priority seats
It is 7.5 because it’s quick maths
Answer:
29.58 mi²
Step-by-step explanation:
The figure is a trapezium and area can be calculated using the formula
A =
h(a + b)
where h is the height and a, b the parallel bases
here h = 3.4, a = 5.4 and b = 12
A = 0.5 × 3.4(5.4 + 12) = 1.7 × 17.4 = 29.58 mi²
