find the circumference of a circle whose area is 6.16sqcm
Answers
Area = πr²
6.16 = 3.14 ×r²
6.16 ÷ 3.14 = r²
r = 1.4 cm
Circumference = 2πr
= 2×22/7×1.4
= 8.8 sq.cm

Answer:
The circumference of a circle is 8.8 cm
Explanation:
Area = πr²
6.16 = 3.14 ×r²
6.16 ÷ 3.14 = r²
r = 1.4 cm
Circumference = 2πr
= 2×π×1.4
= 8.8 cm
The circumference of a circle is 8.8 cm
Multiplication:
To determine the sum of two or more numbers, mathematicians multiply the numbers. It is a basic mathematical procedure that is widely used in daily life. Multiplication is used when we need to mix groups of like sizes. When multiplying two numbers, there is no need to transfer the result over to the next higher place value because the smaller numbers involved are smaller. Before moving on to the more difficult tasks, such as regrouping, the beginner level could aid a learner in understanding the fundamentals of multiplication. The term "multiplication on a number line" refers to performing the multiplication operation on a collection of integers by using a number line.
