Astring of cheese goes around the circumference of a pizza. the pizza has a diameter of 20 cm. what length of cheese is stuffed into the pizza? round to the nearest cm

62.8 cm

Step-by-step explanation:

you need to calculate the circumference of the pizza, and the formula for calculating a circumference of a circle is 2r×π so that means 2×10×3.14=62.8 cm

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
