A basketball has a volume of 5600cm3. what is the approximate radius

Step-by-step explanation:

Sphere Volume = (4/3) * PI * radius^3

radius = cube root (Sphere Volume) / (4/3)*PI

radius = cube root (5,600) / (4/3)*PI

radius = 11.016 cm

radius = 11 cm (rounded)

The area of ​​the triangle is 10 and the semicircle is 39.25

The total area is 49.25cm²

Step-by-step explanation:

Triangle area:

A=(b•h)/2

A=(10•2)/2

A=20/2

A=10

Semicircle area

A=(π•r²)/2

π=3.14 and r=5

A=[3.14•(5²)]/2

A= (3.14•25)/2

A=78.5/2

A=39.25

Area total

At= triangle area+semicircle area

At=39.25+10

At=49.25cm²
