Answer:

49.12 cm²

Step-by-step explanation:

A = b×h/2 + πr²/2

= 8×6/2 + 3.14×16/2

= 24 + 25.12

= 49.12 cm²

Answer:

Exact area = 24+8pi square cm

Approximate area = 49.1327412287183 square cm

================================================================

Explanation:

The semicircle portion has area of 0.5*pi*r^2 = 0.5*pi*4^2 = 8pi

The largest triangle has an area of 0.5*b*h = 0.5*8*6 = 24

The total exact area is therefore 24+8pi and this is approximately equal to 49.1327412287183 after using a calculator.

A circle has an area of 40 square inches. Find the radius to 2 decimal places.

Oksanka [162]

The area of a circle is given by

$A=\pi r^2$

We can solve this equation for r: divide both sides by pi:

$r^2=\dfrac{A}{\pi}$

Consider the (positive) square root of both sides:

$r = \sqrt{\dfrac{A}{\pi}}$

So, in your case, we have

$r = \sqrt{\dfrac{40}{\pi}}\approx 3.57$
