Answer:

A. <u>Volume = 4,523.9 mm³ (cubic mm)</u>

B. <u>Surface area = 1,658.76 mm² (square mm)</u>

Step-by-step explanation:

A. Lest's calculate the volume of the cylinder:

r = 12 mm, h = 10 mm

Volume = π * r² * h

Volume = 3.1416 * 12² * 10

Volume = 3.1416 * 144 * 10

<u>Volume = 4,523.9 mm³</u>

B. Let's calculate the surface area of the cylinder:

Surface area = 2π * r * h +2π * r²

Surface area =2π * 12 * 10 + 2π * 12²

Surface area = 6.2832 * 120 + 6.2832 * 144

<u>Surface area = 753.98 + 904.78 = 1,658.76 mm²</u>

Answer:

45°

Step-by-step explanation:

The angle with measure of 9x and the angle with measure of 3x are supplementary

9x + 3x = 180°

12x = 180 divide both sides by 12

x = 15

The angle with measure of 9x and angle a are supplementary as well

9x + a = 180

9×15 + a = 180

135 + a = 180 subtract 135 ftom both sides

a = 45°

FinnZ [79.3K]

Induced pluripotent stem cells can be a valuable tool in science and medicine because: A. induced pluripotent stem cells can become any cell type in the body, but are from adults, avoiding the controversies associated with embryonic stem cells.

<h3>What is a cell?</h3>

A cell can be defined as the fundamental functional, structural and smallest unit of life, which is typically found in all living organisms.  

In Science, all living organisms are broadly grouped into two (2) main categories according to cell type and these include the following;

  • Unicellular organisms
  • Multicellular organisms

Basically, the reason why induced pluripotent stem cells can be a valuable tool in science and medicine is simply because they can become any cell type within the body of a living organism, but are usually derived from adults that are avoiding the controversies associated with embryonic stem cells.

Complete Question:

Induced pluripotent stem cells are cells from adults that have been reprogrammed to imitate embryonic stem cells. Why might induced pluripotent stem cells be a valuable tool in science and medicine?

A. Induced pluripotent stem cells can become any cell type in the body, but are from adults, avoiding the controversies associated with embryonic stem cells

B. Induced pluripotent stem cells are the only type of stem cell that's truly pluripotent.

C. Induced pluripotent stem cells may become any cell type in the body, but are fraught with ethical questions over their use.

D. Induced pluripotent stem cells are derived from adult cells and therefore may have DNA abnormalities, allowing scientists to understand the effects of sun exposure or toxins on DNA

What is true about the figure?
wlad13 [49]

Answer:

<A = 56degrees

<B = 34degrees

<C = 56degrees

Step-by-step explanation:

From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;

<C + <D = 180

<C + 124 = 180

<C = 180 - 124

<C = 56degrees

Also;

<B + 90 + <C = 180

<B + 90 + 56 = 180

<B  + 146 = 180

<B = 180 - 146

<B = 34degrees

Similarly;

<A + <B = 90

<A + 34 = 90

<A = 90 - 34

<A = 56degrees
