The radius of a semicircular compound is 35 m. What will be its circumference?

Correct option is B

Given:

The radius of the semicircular compound = 35 m

Formula Used:
The total circumference C of a semicircle is given by:

C = πr + 2r

where:

r is the radius of the semicircle,

Solution:

Use the given radius r = 35 m in the formula:

C = $$\pi \times 35 + 2 \times 35$$​

C = $$\frac{22}7 \times 35 + 70$$​

C = 110 + 70 = 180 m
The circumference of the semicircular compound is 180 m.
