For both problems, they want you to check their answers. For #1, is the opposite of -12 + 4 eight? For #2, can you split an 8 oz bag into 13 to have 2/3 oz in each bag? If you want the answers I’d be happy to comment. :)

The circle above has a radius of 11 cm. What is the area of the circle
Fittoniya [83]

Answer:

69. 14cm^{2}  or    22πcm^{2}

Step-by-step explanation:

Area of a circle = 2πr

and, radius, r = 11 cm

π = 22/7

Therefore the area of a circle with radius 11cm

= 2* π * 11          or      2 * 22/7 * 11

= 22π                or       = 484/7

                                 = 69. 14cm^{2}

If a sphere’s volume is doubled, what is the corresponding change in its radius?
velikii [3]
           Volume of a sphere = (4/3) (pi) (radius)³

The sphere's volume is proportional to the cube of its radius,
so the radius is proportional to the cube-root of the volume.

The only way to double a sphere's volume is to increase
its radius by the factor of
                                              ∛2 = 1.26 (rounded).
