Choose all that compute the correct area of the circle. Use π = 3.14.

The area of a circle with a diameter of 5 cm.
A ≈ 19.63 cm2

The area of a circle with a radius of 3 cm.
A ≈ 28.26 cm2

The area of a circle with a diameter of 4 cm.
A ≈ 50.27 cm2

The area of a circle with a radius of 7 cm.
A ≈ 153.86 cm2

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

answer: $1794
