Question

The radius of a semicircular garden is 28 m. How
much more distance has one to cover for going from A
to B on the circular path instead of going on diametri-
cal path? (Choose two correct alternatives.)
(1) 7.2 m (2) 32 m (3) 0.32 hm (4) 320 cm
​

Answer 1

Answer:

Options (2) and (3)

Step-by-step explanation:

Given,

radius of semi-circular garden (r) = 28m

length of diameter (d) = 56m

Shortest distance from A to B = d =56m

Distance around the semicircular garden = circumference of the garden

=> πr

= 22/7 × 28

= 88m

Extra distance that one needs to cover = c - d

=88 - 56

=32m (or) 0.32hm

Hope it helps.
