Answer:

-4.88

Step-by-step explanation:

-5+(-3) = (-8)

7/10 = 98/140

3/7 = 60/140

15/4 = 525/140

525/140 + 60/140 + 98/140 = 683/140

683/140 = 4 123/140

4 123/140 = 4.88 (2dp)

4.88+(-8) = -4.88

Which of the following equations could be solved for a radius? Select all that apply.
zalisa [80]

Answer:

A = π · (r²)

Step-by-step explanation:

A =π · r² is the area of a circle.

While π · r² · h can also give you the radius, it can only do so for the Volume V, not the Area A.

V=lwh doesn't really apply for a circular object, as it requires the length and width. For circular objects, both are equal to the diameter of the object, and 2² · r² · h does not equal the Volume.

V= π · r³ seems awfully like the volume of a sphere, but there's something missing. The true volume of a sphere is V=\frac{4}{3} · π · r³, not V= π · r³.

A=\frac{1}{2}*b*h only applies for triangles.
