Arc length has a formula that is similar to arc measure, but arc length is expressed in inches or meters or miles, etc., whereas measure is expressed in degrees, like an angle.  The formula for each take this into account.  Since the arc length is part of the length of the outside of the circle, the formula includes the circumference for a circle.  AL= \frac{ \theta }{360} * \pi d, where theta is the degree measure of the central angle intersecting the arc you're looking for, and d is the diameter of the circle.  Our formula would look like this with the info we have: AL= \frac{30}{360}* 24 \pi which can be simplified to AL= \frac{1}{12}*24 \pi which can be simplified even further to AL=2 \pi.  And that's your answer!

Two paths each 2m wide run across the middle of a rectangular field. If the area of the cross path is 196m and its length is 60m
Naddik [55]

Answer:

d=2m

Area(A)=196m

l=60m

Now,

A=d(l+b-d)

196=2(60+b-2)

196=2(58+b)

196=116+2b

2b=196-116

2b=80

b=40m

Jlenok [28]

Question:

A solar lease customer built up an excess of 6,500 kilowatts hour (kwh) during the summer using his solar panels. when he turned his electric heat on, the excess be used up at 50 kilowatts hours per day .

(a) If E represents the excess left and d represent the number of days. Write an equation for E in terms of d

(b) How much of excess will be left after one month (1 month = 30 days)

Answer:

a. E = 6500 - 50d

b. E = 5000

Step-by-step explanation:

Given

Excess = 6500kwh

Rate = 50kwh/day

Solving (a): E in terms of d

The Excess left (E) in d days is calculated using:

E = Excess - Rate * days

The expression uses minus because there's a reduction in the excess kwh on a daily basis.

Substitute values for Excess, Rate and days

E = 6500 - 50 * d

E = 6500 - 50d

Solving (b); The value of E when d = 30.

Substitute 30 for d in E = 6500 - 50d

E = 6500 - 50 * 30

E = 6500 - 1500

E = 5000

<em>Hence, there are 5000kwh left after 30 days</em>
