Find the total surface area of the pyramid

Mathematics
1 answer:
quester [9]3 years ago
3 0
To find the surface area of a pyramid, we need to find the area of all the faces and add them up. 

4 * 6 = 24
24 / 2 = 12

There are four sides (not including the base) in this pyramid, so we should multiply this by 4. 

12 * 4 = 48

Now, we find the area of the base.

6 * 6 = 36

We add up all of the numbers:

48 + 36 = 84

84 in^2 is the answer. 

Hope this helps!

Need help with this NOW plzzzzz!!!!
Mazyrski [523]
Hello!

The circumference is the diameter multiplied by pi, or the distance around a circle. Since we already have the circumference, and need to find the diameter, we will divide the circumference by pi(3.14).

113.04/3.14=36

The diameter of the circle is 36 units.

I hope this helps!

The medicine capsule shown consist of a cylinder with a hemisphere at each end. The total length of the capsule is 15 millimeter
sweet [91]

Answer:

The surface area of capsule is 235.5 mm².

Step-by-step explanation:

Given that,

Diameter = 5 mm

Total length = 15 mm

We need to calculate the radius of each hemisphere

Using formula of radius of hemisphere

\text{radius of each hemisphere}=\text{radius of cylinder}

r=\dfrac{5}{2}

r=2.5\ mm

We need to calculate the length of cylinder

Using formula of length

Length of cylinder = Total length of capsule-radius of left hemisphere- radius of right hemisphere

\text{length of cylinder}=15-2.5-2.5

\text{length of cylinder}=10\ mm

We need to calculate the surface area of capsule

Using formula of surface area of capsule

\text{surface area of capsule}=\text{Curved surface area of cylinder}+\text{surface area of left hemisphere}+\text{surface area of right hemisphere}

\text{surface area of capsule}=2\pi rl+2\pi r^2+2\pi r^2

\text{surface area of capsule}=2\pi rl+4\pi r^2

Put the value into the formula

\text{surface area of capsule}=2\times3.14\times2.5\times10+4\times3.14\times(2.5)^2

\text{surface area of capsule}=235.5\ mm^2

Hence, The surface area of capsule is 235.5 mm².
