Answer:
Step-by-step explanation:
The given figure is a trapezoid. The perimeter of a plane figure is expressed as the the distance around the figure. Therefore
Perimeter = a2 + b2 + a1 + b1
Perimeter = 4.7 + 5.8 + 8.5 + 6.89 = 25.89 feet
The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of The bases are the 2 sides of the trapezoid which are parallel with one another.
h represents the height of the trapezoid.
From the diagram,
a = 4.7 feet
b = 8.5 feet
h = 5.8 feet
Area = 1/2(4.7 + 8.5)5.8
Area = 1/2 × 13.2 × 5.8
Area = 38.28 feet²
Answer:
C. Amount needed to fence around a circular garden
Step-by-step explanation:
The Circumference of a circle can be referred to as the length of the circle. It also called the perimeter of a circle.
The circumference of a circle can be defined as the distance roundabout a circle.
The circumference of a circle is calculated mathematically as:
a) 2πr or
b) πD
Where r = radius of the circle.
D = Diameter of the circle
From the above question, the situation can be modeled by circumference of a circle based on the definition that the circumference of a circle is the distance around a circle is Option C. "Amount needed to fence around a circular garden"
I believe it would be -4/3.
Answer:
Both the radius and height of the cylinder are 2.48 cm.
Step-by-step explanation:
V = π r2 h
(where r is the radius and h is the height.)
However, in the problem statement, we were told that the radius equals the height or "r = h"
So, we can rewrite the above equation as:
V = π r2*r = π r3
Now we just have to solve for r
r3 = V/π
r = (V/π)1/3
r = (48/π)1/3=2.48 cm
