Question

calculate the radius of the semi circle if the diameter is 12cm

Answer 1

Question:

Calculate the radius of semi-circle if the diameter is 12cm.

Given:

Diameter of semi-circle= 12cm.

To Find:

Radius of Semi-circle.

Explanation:

Radius of the Semi-circle is always half times of Diameter. So,

$r=\large\frac{d}{2}$

Where,

r= Radius of semi-circle

d= Diameter of semi-circle

Solution:

---› $\mathsf{r=\large\frac{d}{2}}$

---› $\mathsf{r=\large\frac{12}{2}}$

---› $\mathsf{r=6}$

Final Answer:

Radius of the Semi-circle is 6cm.

More To Know:

Perimeter of semi-circle=πr+2r

Area of semi-circle=$\large\frac{(πr)²}{2}$
