solve this question in maths in 7th standard measurement lesson
Diameter : 25 m.
Radius. : ?
Circumference : ?.
solve these questions and tell The answer for radius and circumference of the circle .​

Answer 1

Answer:

Radius - 12.5

Circumference - 78.54

Step-by-step explanation:

Radius is half of diameter. r = d/2

half of 25 is 12.5

circumference is 2πr.

2 x 22/7 x 12.5 = 78.54

Answer 2

Answer:

Radius=12.5 m

Circumference= 78.5

Step-by-step explanation:

Radius = $\frac{Diameter}{2}$

Radius = $\frac{25}{2}$ = 12.5 m

Circumference = 2 π R

                          = 2 × 3.14 × 12.5

                          = 78.5 m
