Answer:
69. 14
or 22π
Step-by-step explanation:
Area of a circle = 2πr
and, radius, r = 11 cm
π = 22/7
Therefore the area of a circle with radius 11cm
= 2* π * 11 or 2 * 22/7 * 11
= 22π or = 484/7
= 69. 14
Answer:
32.40cm²
Step-by-step explanation:
Given the parallelogram ABCD ;
side AB is always Parallel to CD, hence ;
AB = CD = 7.2cm
Perpendicular from C on AB is the height of the parallelogram = 4.5cm
Area of a parallelogram : base * height
Area of a parallelogram = length base * height
Area of a parallelogram = 7.2 cm * 4.5cm
Area of parallelogram = 32.40cm²
For a pear, it would be 3/16 of a chance. For an orange, it would be 1/4 of a chance.
It would be 70% of 400
490(.7) = 280
