Answer:
Area = 733 m² (to the nearest meter)
Step-by-step explanation:
<u></u>
<u>Formulae</u>
- Circumference of a circle = 2
r - Area of a circle =
r²
(where r is the radius of the circle)
<u>Find the radius</u>
circumference = 96 m
Using the circumference of a circle formula:
⇒ 2
r = 96
⇒
r = 96 ÷ 2 = 48
⇒ r = 48 ÷
= 48/
<u>Find the area</u>
radius r = 48/
Using the area of a circle formula:
⇒ A =
r²
⇒ A =
(48/
)²
⇒ A = 2304/
⇒ A = 733.3859778...
⇒ A = 733 m² (to the nearest meter)
Which equation represents a proportional relationship?
C. y=1/2x+3
The total length of the steel used in the frame is 270 cm, if the decorative steel up of 6 stems and each stem is 45 cm.
Step-by-step explanation:
The given is,
Decorative steel made from circular circle of 6 stems
The length of the stem is 45 cm
Step:1
We need to find the total length of the steel used in the decorative steel,
Let, T - Total length of the steel
L - Length of the stem
n - Number of stems used in steel frame
Step:2
Formula to find the total length of the steel is,
× 
From given,
= 45 cm
= 6 stems
Substitute the values in formula,
( 45 × 6 )
= 270
270 cm
Result:
The total length of the steel used in the frame is 270 cm.
