Which statement about Eduardo’s calculations is true?

Mathematics
1 answer:
jeyben [28]3 years ago
3 0

Answer:

"Eduardo did not use the correct formula for the circumference"

Step-by-step explanation:

The circumference formula is  C = 2πr

Area formula is  A=πr^2

Volume formula is correct. The steps area also correct to find r, the radius.

But in the end, he put the formula for circumference wrong. He used the formula for Area, NOT Circumference.

Hence, "Eduardo did not use the correct formula for the circumference" should be the correct choice for this question.

Find the the length of the unknown side round to the nearest tenth
andrew11 [14]

Answer:

The length of the missing side b would be 16m

Step-by-step explanation:

first you would use the formula a2+b2=c2

12^2+b2=20^2

-take 12*12 and 20*20

144+b2=400

-subtract 144 from 400 in order to get b2 alone

b2=256

-take the square root of b and 256

b=16

Find the number, 112/ 100 of it is 56
Alinara [238K]
First let that number be y.
List the equation by the given info.
y x 112/100 = 56
Shift y to the other side by turning it to ÷y.
112/100 = 56/y
Use cross method,
100 x 56 = 112y
5600 = 112y
y = 50
Therefore that number is 50

In parallelogram LMNO, what is the measure of angle M? please helppppp
laiz [17]

Answer:

80 degrees

Step-by-step explanation:

First find the the angles N and L:

5x=3x+40

2x=40

x=20

m<N= 100 m<L=100

Now we know that the sum os all Interior angles of a parallelogram is 360

and you know that opposite sides are equal

hence,

2y= 360-2(100)   y being angle M (or o)

2y= 160

y=80
