Answer:

The area is 88.39 cm

Step-by-step explanation:

Here, we want to find the area of the semicircle given that the diameter of the semi circle is 15 cm

We start by getting the radius

Mathematically r = D/2

= 15/2 = 7.5

Area of semicircle is area of circle/2

= (pi * r^2)/2

= (22/7 * 7.5^2)/2 = 88.39 cm

Answer:

( $8v^2-15w^5)(8v^2+15w^5)$

Step-by-step explanation:

STEP 1:

$8^{2}$ $v^{2*2}$ - $15^{2}$ $w^{2*5}$

STEP 2:

$8^{2}$ * $(v^{2})^{2}$ - $15^{2} * (w^{5})^{2}$

STEP 3:

$(8v^2)^2 - (15w^5)^2$

STEP 4:

( $8v^2-15w^5)(8v^2+15w^5)$
