The area of a circle is 8π square units. What is the radius of the circle in simplest radical form?

Sav [38]

Answer:

Step-by-step explanation:

The area of a circle is :A= π r² r : the radius

A= 8π square units

so : π r² = 8π

r² = 8

r = √8 = √(4 × 2) =√4×√2

r = 2√2 units

Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so much!

Anestetic [448]

Answer:

Step-by-step explanation:

Radius =6 ft

Area of circle = πr²

= 3.14 * 6 * 6

= 113.04 ft²

base = 10.39 ft

height = 6+3 = 9 ft

$Area \ of \ triangle = \dfrac{1}{2}*base * height\\\\\\=\dfrac{1}{2}*10.39*9\\$

= 46.76 ft²

Area of the shaded region = area of circle - area of triangle

= 113.04 - 46.76

= 66.28

= 66.3 ft²

Answer:

58,187.5 m²

Step-by-step explanation:

1 cm : 25 m

7 cm = 25 × 7 m

7 × 25 = 175 m

13.3 × 25 = 332.5 m

area = 332.5 m × 175 m
