Red Given:
- Length of base is "6cm50mm"
- length of base= 11cm
- Height is "400mm"
- height= 40 cm
Red Solution:
- Area of triangle =1/2bh
- ar.(triangle)=1/2(11cm)(40cm)
- ar.(triangle)=(11cm)(20 cm)
Orange ar.(Triangle)=220cm^2
Answer:
The area of the circle = 27.0212cm^2
Step-by-step explanation:
The area for a circle is
A = πr^2
But weve been given the area of the circle in the information provided above
Area of a circle is given as
A = ttr
Where,
A - area of circle
r = radius of the circle
We've been the values of r and tt
r = 8.6cm
tt = 3.142
Inserting the values given into
A = ttr
A = 3.142 * 8.6
A = 27.0212cm^2
The area of the circle is 27.0212cm^2
