Please help me with this!!
bearhunter [10]

Answer:

8.06

Step-by-step explanation:

Use the Pythagorean theorem:

a^{2} +b^{2} =c^{2}

The hypotenuse is always the slanted side, or c (x in this picture), but the other numbers can be interchanged. Doesn't matter.

Plug the numbers 4 and 7 into the formula.

4^{2} +7^{2} =c^{2} \\

Now evaluate them to get c^2

16+49=65

To get c, take the square root of 65

\sqrt{65}  = 8.06

Trig: A sector of a circle has area 25 cm2 and centralangle
Alchen [17]

Answer:  Radius = 10 cm and Arc length = 5 cm

Step-by-step explanation:

The area of a sector with radius r and central angle \theta (In radian) is given by :-

A=\dfrac{1}{2}r^2\theta

Given : A sector of a circle has area 25 cm^2 and central angle  0.5 radians.

Let r be the radius , then we have

25=\dfrac{1}{2}r^2(0.5)\\\\\Rightarrow\ r^2=\dfrac{2\times25}{0.5}\\\\\Rightarrow\ r^2=\dfrac{50}{0.5}=100\\\\\Rightarrow\ r=\sqrt{100}=10\ cm

Thus, radius = 10 cm

The length of arc is given by :-

l=r\theta=10\times0.5=5\ cm

Hence, the length of the arc = 5 cm
