The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
s = (2\pi  r)( \frac{x}{360})
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.

s = 2π(3.5)(1/2) ≈ 11.00

Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.

Spencer wants to burn 450 calories while biking. Biking burns about 10 calories per minute. When Spencer goes biking, he usually
kupik [55]

Answer:

The equation  to find the total number of minutes (including rest) that Spencer should plan to be out biking is 10(m-15)=450.

Spencer should plan for 60 minutes  to be out biking.

Step-by-step explanation:

Given:

Total calories need to burn = 450 calories

Calories burn per minute = 10

number of minutes he rest = 15

We need to find the total number of minutes (including rest) that Spencer should plan to be out biking.

Solution:

Let Total minutes of biking be 'm'.

So we can say that.

Calories burn per minute multiplied by the difference of total minutes and number of minutes he rest is equal to Total calories need to burn.

framing in equation form we get;

10(m-15)=450

Hence the equation  to find the total number of minutes (including rest) that Spencer should plan to be out biking is 10(m-15)=450.

On Solving the above equation we get;

First we will divide both side by 10 we get;

\frac{10(m-15)}{10}=\frac{450}{10}\\\\m-15=45

Now adding both side by 15 we get;

m-15+15=45+15\\\\m=60\ minutes

Hence Spencer should plan for 60 minutes  to be out biking.
