Question

7. If perimeter of equilateral triangle with side 44cm is equal to circumference
circle. Then radius of circle is...​

Answer 1

Answer:

the radius of the circle 44/3=14.5.

Answer 2

Answer:

r = 21 cm

Step-by-step explanation:

Perimeter of equilateral triangle = 3a

• a = 44cm

$circmference \: of \: a \: circle \: = \: 2\pi \: r$

perimeter of equilateral triangle = circumference of a circle

$3 \times 44 = 2 \times 22 \div 7 \times r$

$132 = 44 \div 7 \times r$

$r \: = \: 132 \times 7 \div 44$

$r \: = \: 924 \div 44$

$r = 21cm$

Therefore, the radius of the circle is equal to 21cm.
