Answer: 314cm

Step-by-step explanation:

The area of a circle = πr^2

where π = 3.14

r = radius

From the question, we've been given the radius as 10cm. So, we plug the radius into the formula.

Area= πr^2

= 3.14 × (10 × 10)

= 3.14 × 100

= 314 cm

Answer:

Step-by-step explanation:

Given a composite figure,

A circle of radius r = 10cm

We want to find the area of the circle?

Area of a circle is calculated using

A = πr²

Where π is given to be 3.14

π = 3.14

And r is the radius of the circle

Then, area of the composite figure is

A = πr²

A = 3.14 × 10²

A = 3.14 × 100

A = 314 cm²

The last option is correct

Area of a triangle is,

$a = \frac{1}{2} ( bh)$

Substitute the numbers,

$210 = \frac{1}{2} (35 \times x)$

$x = 12$

The above number is the base.

Using the pythagorean method let's calculate for "c" the hypotenuse.

$c = \sqrt{ {a}^{2} + {b}^{2} }$

Substitute

$c = \sqrt{ {35}^{2} + {12}^{2} }$

Solve,

$c = \sqrt{1225 + 144}$

Simplify,

$c = \sqrt{1369}$

Calculate one last time,

$c = {37}$

The hypotenuse is 37 inches.
