Answer:

  1. The error is that he made the radius a diameter.
  2. The circumstances is 150.8571428 m

Step-by-step explanation:

π = 22/7 or 3.14

Circumference= diameter × 22 / 7

= 2 × radius × 22 / 7

= 2 × 24 × 22/ 7

= 48 × 22 / 7

= 48 / 1 × 22 / 7

= 1056 / 7

= 150.8571428 m

Answer:

11. The student put 24 as the diameter instead of the radius.

12. 48 pi

Step-by-step explanation:

The formula for the circumference of a circle is c = pi x diameter.

However, the question says that the radius is 24m, not the diameter.

To fix it, all you need to to is double the radius to get 48m for the diameter.

48 x pi = 48 pi

madam [21]

Answer:

$20

Step-by-step explanation:

The large ones cost $4 more so what you would do is to subtract that $4 from the $24.

PLEASE HELP!!!!!!!
Leno4ka [110]

Answer:

(a)

degree is 4

it is binomial

(b)

degree is 2

it is trinomial

(c)

degree is 3

it is monomial

Step-by-step explanation:

(a)

we are given function as

f(x)=5x^4-8

Degree:

we know that degree is highest exponent value

so, degree is 4

Number of terms:

we can see that there are two terms

so, it is binomial

(b)

we are given function as

f(a)=4a^2-2a-16

Degree:

we know that degree is highest exponent value

so, degree is 2

Number of terms:

we can see that there are three terms

so, it is trinomial

(c)

we are given function as

f(m)=9m^3

Degree:

we know that degree is highest exponent value

so, degree is 3

Number of terms:

we can see that there are one term

so, it is monomial

Circle experts...help! will give brainly to most detailed answer

<h3>Answer:  161 degrees</h3>

=========================================================

Explanation:

Line AE is a tangent while line AU is a secant. The angle formed by the secant and tangent lines connects with the arcs through this formula

secant tangent angle = (larger arc - smaller arc)/2

More specifically, we can say:

angle EAI = (arc EU - arc IE)/2

42 = ( (7m+5) - (3m-1) )/2

42*2 = (7m+5) - (3m-1)

84 = 7m+5 - 3m+1

84 = 4m+6

4m+6 = 84

4m = 84-6

4m = 78

m = 78/4

m = 39/2

m = 19.5

Use this value of m to compute each arc

  • arc IE = 3m-1 = 3*19.5-1 = 57.5 degrees
  • arc EU = 7m+5 = 7*19.5+5 = 141.5 degrees

Let's say arc IU is some unknown number x. It must add to the other two arc measures to form 360 degrees, which is a full circle.

(arc IU) + (arc IE) + (arc EU) = 360

x + 57.5 + 141.5 = 360

x + 199 = 360

x = 360-199

x = 161

The measure of minor arc IU is 161 degrees
