Answer:
19
Step-by-step explanation:
Given
(6 + h² - j) ÷ 2 , substitute h = 6 and j = 4 into the parenthesis
= (6 + 6² - 4) ÷ 2
= (6 + 36 - 4) ÷ 2
= 38 ÷ 2
= 19
Answer:
the answer is 516
Step-by-step explanation:
you would multipy the SA by the scale factor and get B
The arc length by definition is given by:
S = R * Theta
Where,
R: radio
Theta: central angle
Substituting values we have:
S = (5.8) * (5.4)
S = 31.32 inches
Answer:
The value of s, the arc length (measured in inches) is:
S = 31.32 inches
X + y = 47
x = y + 13
y + 13 + y = 47
2y + 13 = 47
2y = 47 - 13
2y = 34
y = 34/2
y = 17
x = y + 13
x = 17 + 13
x = 30.....longer piece is 30 inches
Answer:
area of the sector = 360π cm²
Step-by-step explanation:
To calculate the area of the sector, we will follow the steps below;
First write down the formula for calculating the area of a sector.
If angle Ф is measured in degree, then
area of sector = Ф/360 × πr²
but if angle Ф is measured in radians, then
area of sector = 1/2 × r² × Ф
In this case the angle is measured in radiance, hence we will use the second formula
From the question given, radius = 15 cm and angle Ф = 8π/5
area of sector = 1/2 × r² × Ф
=1/2 × 15² × 8π/5
=1/2 ×225 × 8π/5
=360π cm²
area of the sector = 360π cm²
