Answer:

1.) 10 cm

2.) 4 cm

3.) A lid of pitcher

4.) Central Angle

Step-by-step explanation:

NOTE:

Diameter is twice the radius.

1.) Given: r = 5cm

d = ?

d = 2r

d = 2(5 cm)

d = 10 cm✔️

2.) Given: d = 8 cm

r = ?

Since, the diameter is given, use the formula d = 2r.

d = 2r

divide both sides by two to get the formula for r.

r = d/2

= 8cm/2

r = 4 cm ✔️

3.)

Diameter of upper edge bowl = 15 meters

Diameter of a lid of pitcher w/ a radius of 8 meters: d = 2r, d = 2(8meters) = 16 meters.

Therefore, a lid of pitcher has a longer diameter.
