Answer:

236.715 ft²

Step-by-step explanation:

The figure consists of the rectangle with sides 15 ft and 4 ft and two semicircles with diameter 15 ft (radius 7.5 ft).

The area of the rectangle is

A₁=15·4=60 ft²

The area of two semicircles together is the area of circle. Thus,

A₂=πr²=π·7.5²=56.25π≈176.715 ft²

The area of the figure is

A=A₁+A₂=60+176.715=236.715 ft²

¹¹/48 of the full cup

Step-by-step explanation:

We add the two fraction first to determine the total ratio

¹/4 + ²/3 = ¹¹/12

She uses ¼ cup grape juice for ¹¹/12 cup full of diluted grape juice

Therefore;

¼ : ¹¹/12

How How much grape juice does Sarah use for each full cup of water, i.e ¹²/12

? (x) : ¹²/12

We cross multiply the ratios;

¹²/12 * ¼ = ¹¹/12 * x

³/12 = ¹¹/12 x

³/12 * ¹²/11 = x

¹¹/48 = x
