Step-by-step explanation:
Amount of green clay at the start = 57g + 31g = 88g.
Amouny of green clay used = 88g - 18g = 70g.
Hence 70g of green clay was used during the week.
Radians = degrees ×π/180
radians= -60×π/180
radians= -π/3

Answer:
90
Step-by-step explanation:
interior angles of all triangles add up to 180 degrees
180=x+5+x-5+2x
180=4x
45=x
plug back in to find largest angle
2 (45) = 90
Answer:
1.243 cm
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of the two congruent circular bases and the rectangular lateral area.
![SA = 2\pi r^2 + 2 \pi rh](https://tex.z-dn.net/?f=%20SA%20%3D%202%5Cpi%20r%5E2%20%2B%202%20%5Cpi%20rh%20)
![SA = 2\pi r(r + h)](https://tex.z-dn.net/?f=%20SA%20%3D%202%5Cpi%20r%28r%20%2B%20h%29%20)
We are given the surface area and the diameter.
r = d/2 = 7 cm / 2 = 3.5 cm
We can solve for h, the height.
![SA = 2\pi r(r + h)](https://tex.z-dn.net/?f=%20SA%20%3D%202%5Cpi%20r%28r%20%2B%20h%29%20)
![2\pi r(r + h) = SA](https://tex.z-dn.net/?f=%202%5Cpi%20r%28r%20%2B%20h%29%20%3D%20SA%20)
![r + h = \dfrac{SA}{2\pi r}](https://tex.z-dn.net/?f=%20r%20%2B%20h%20%3D%20%5Cdfrac%7BSA%7D%7B2%5Cpi%20r%7D%20)
![h = \dfrac{SA}{2\pi r} - r](https://tex.z-dn.net/?f=%20h%20%3D%20%5Cdfrac%7BSA%7D%7B2%5Cpi%20r%7D%20-%20r%20)
![h = \dfrac{104.3~cm^2}{2(3.14159)(3.5~cm)} - 3.5~cm](https://tex.z-dn.net/?f=%20h%20%3D%20%5Cdfrac%7B104.3~cm%5E2%7D%7B2%283.14159%29%283.5~cm%29%7D%20-%203.5~cm%20)
![h = 1.243~cm](https://tex.z-dn.net/?f=%20h%20%3D%201.243~cm%20)
