emmasim [6.3K]

Answer: The area of the regions covered by grass is approximately 313.375 sq ft.

Step-by-step explanation:

Given: A company is building a new park in the shape of a circle with a 25 ft diameter.

Then radius = $\dfrac{25}{2}=12.5\ ft$

Required area = Area of circle - Area of rectangle + Area of triangle

Formula: Area of circle = $\pi r^2$

Area of rectangle = length x width

Area of triangle = 0.5 x base x height

Area of circle = $(3.14)(12.5)^2=490.625\ \text{ft}^2$

Area of rectangle = 20 ft x 10ft = 200 ft²

Area of triangle = 0.5 x 7 x 6.5 = 22.75 ft²

Required area = 490.625 -200+22.75 = 313.375 ft²

Hence, The area of the regions covered by grass is approximately 313.375 sq ft.

Referring to the figure, find the volume of the solid<br> shown. Round to the nearest whole number.

mr_godi [17]

Answer:

846 m³

Step-by-step explanation:

The solid consists of a rectangular prism and a rectangular pyramid.

V = LWH + (1/3)LWh

V = 9 m * 6 m * 12 m + 1/3 * 9 m * 6 m * 11 m

V = 648 m³ + 198 m³

V = 846 m³
