Plz plz plz help me solving this question ​

Perimeter: 19 cm ( I added 5.5+7.5+6)

The length of each side of the square: 8 cm

We know that the area is 64 cm2

A=a*a (length times length) We get 8 (because we know the times tables)

Volume: 100

3.950121805833336 ≈ 4 m

Step-by-step explanation:

The area of a circle is calculated using this formula: A= πr². Since we know the area of the circle is 154 we have all the values we need to solve this problem.

154 = πr²

√154 = πr

12.40967... = πr

12.40967.../π = r

3.950121805833336 = r

3.950121805833336 ≈ 4 meters

need more information

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
