anygoal [31]

A = l*w
l = 2w + 4
400 = (2w + 4)*w
0 = 2w^2 + 4w - 400

Then use the quadratic equation where a=2, b=4, and c=-400.

w = <span>13.2
l = 30.4

Preston has calculated that his drink coaster has an area of 78.5 square centimeters.What is the coaster’s radius? Use 3.14 for

Alexandra [31]

Answer:

The coaster’s radius is 5 cm

Step-by-step explanation:

Drink Coaster has a circular shape.

Area of a circle = π*r²

so, area of the drink coaster = π x (Radius of the drink coaster)²

Given that Area of the drink coaster is 78.5 cm²

∴ 78.5 cm² = π*r²

Also we are to use 3.14 for π

∴ 78.5 cm² = 3.14*r²

r² = 78.5 cm² / 3.14

r² = 25 cm²

r = $\sqrt{25}$ cm

r = 5 cm

Hence, the coaster’s radius is 5 cm
