Once
25 / 16 = 1 remainder 9
or we can write the quotient as 1 9/16
Answer:
Total area is 198.6cm²
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes.
Step one
From the given figure the two semi circles left and right can be resolved as a whole (a complete circle) with diameter d 10cm
Radius r = 10/2= 5cm
Area of circle A= πr²
A= 3.142*5²
A= 3.142*25
A= 78.55
A= 78.6cm²
Step two
The remaining part of the shape is a rectangle with length (22-10)= 12cm
I.e the 10 is as a result of the radius of the two semi circles = r+r= 5+5=10
The rectangle has a width of 10cm
Area of rectangle A=12*10= 120cm²
Hence the total surface area of the shape
Total area = 120+78.6
Total area = 198.6cm²
Answer:
1) Arc length = 2πr ( Ф/360)
= 2 × 22/7 × 15 (120/360)
= 44/7 × 15 (1/3)
= 44 × 5/7
= 31.428 in
2) Arc length = 2πr ( Ф/360)
= 2 × 22/7 × 14 (90/360)
= 44/7 × 14 ( 1/4)
= 616/7 × (1/4)
= 88 (1/4)
= 22 yards
Hope it helps!!!
Answer:
The Proof is below.
Step-by-step explanation:
Given:
[]MNOP is a Parallelogram
U is any point on side OP
To Show:
ar(Δ MUN)= ar ( Δ PUM)+ar (Δ UNO)
Proof:
Theorem:
If a triangle and parallelogram are on the same base and have the same altitude, the area of the triangle will be half that of the parallelogram.
If they have same altitude, they will lie between the same parallels.
Hence the area of the triangle will be equal to half that of the parallelogram.
Area of Parallelogram will be twice of Area of Triangle
∴ 
.............( 1 )
Also,
Substituting equation 1 we get
