Answer:

81π cm²

≈254.34 cm²

Step-by-step explanation:

The area formula for a circle is π×r².

Since the radius of the pizza is 9, we get:

π×9²=

2×π×81=

81π or ≈ 254.34 cm²

Answer:

Step-by-step explanation:

Pi x radius^2 = Area of a circle

3.14 x 9cm^2 = 3.14 x 81cm = 254.34 cm squared

Find the measure of angle x

Triss [41]

Answer:

it is heptagon and sum of interior angles of heptagon is 900 °

123°+131°+ 125°+124°+x 129°+132° = 900°

764° +x = 900 °

x = 900°-764°

x = 136°

What is the area of the figure below ?

Airida [17]

Answer:

Step-by-step explanation:

Area of the figure = area of the down triangle + area of trapezium + area of the upper triangle

Down triangle:

Base b = 8 in

Height = 6 in

$Area = \frac{1}{2}bh\\=\frac{1}{2}*8*6\\\\=4*6$

= 24 in²

Trapezium:

bases a = 4 in & b = 6 in

Height h = 5 in

$Area=\frac{(a+b)h}{2}\\\\=\frac{(4+6)*5}{2}\\\\=\frac{10*5}{2}\\\\=5*5$

= 25 in²

Area of the upper triangle:

Base b = 6 in

Height = (8 - 5) = 3 in

$Area=\frac{1}{2}bh\\\\=\frac{1}{2}*6*3\\\\=3*3$

= 9 in²

Area of the figure = 24 + 25 + 9 = 58 in²
